    ABSTRACT: Based on detailed kinetic studies on these systems, plausible reaction schemes have been proposed that account for the experimental observations; component rate constants of the derived rate-laws have been evaluated by graphical/least square procedure. The results indicated the reactivity order thiosemicarbazide > amidinothiourea >> biguanide. The results of the amidinothiourea system afford a meaningful comparison with the corresponding results for the tetrachloroplatinate(II) reported by us previously (see text); k(Pd)/k(Pt) is of the order of 10(4). Comparison of the Delta S-# values for the two systems suggests that in both the cases the reaction proceeds by an interchange process with bond formation being significant in case of Pt(II) while bond dissociation is significant in case of Pd(II).

    ABSTRACT: Food industry is a major source of waste water pollution. Several techniques are available to remove pollutants from food industry waste water. One of the promising technologies for the removal of pollutants from food industry waste water is coagulation and flocculation. In the present work, various coagulants like lime,, alum and ferrous sulphate were applied on waste water to select the suitable one with optimum removal efficiencies for further treatment with polyelectrolytes. Parameters such as turbidity, Total suspended solids (TSS), Chemical oxygen demand (COD), Biological oxygen demand (BOD) and oil and grease content were evaluated. On the basis of results, lime was proven to be the most efficient inorganic coagulant for further treatment. It could remove 55.2% turbidity, 51% TSS, 49.6% COD, 51% BOD and 51% oil and grease at its optimum dosage of 50 mg/L. Generation of sludge in the coagulation-flocculation process was also studied. The volume of sludge was 22.5 mg/L at the optimum dosage of lime. Further cationic polyelectrolyte Organopol 5470C and anionic polyelectrolyte Chemfloc 430A were also studied in conjunction with lime. Organopol 5470C in conjunction with lime showed better result because of low dosage, maximum pollutant removal and minimum quantity of sludge generation. It could remove 94% turbidity, 95.5% TSS, 83.5% COD, 89% BOD and 92.5% oil and grease; whereas Chemfloc 430A in conjunction with lime could remove 91.2% turbidity, 90% TSS, 77.8% COD, 83% BOD and 86.8% oil and grease. The volume of sludge produced while using polyelectrolyte and lime together was much lower than using lime alone. The amount of sludge produced in case of Organopol 5470C and lime together is 8.9 mg/L, while sludge generation by Chemfloc 430A in conjunction with lime is 10.4 mg/L.

    ABSTRACT: Kinetic and mechanistic study of oxidation of methylparaben by permanganate in acidic medium was carried out spectrophotometrically at 25 degrees C. The stoichiometric ratio between permanganate and methylparaben was found to be 2 : 2. The results have shown that the reaction was first-order with respect to permanganate concentrations and has less than unit order with respect to methylparaben. As the concentration of perchloric acid increases, the rate of reaction also increases. The order with respect to acid concentration was found to be fractional. The oxidation products were identified by spectral studies. The effect of ionic strength, dielectric constant and initially added product were studied on the rate of reaction. A suitable mechanism was proposed on the basis of experimental results. Methylparaben binds to permanganate to form a complex that subsequently decomposes to the products. The reactions were carried out at different temperatures allowing the determination of the activation parameters with respect to slow step by Arrhenius equation and thermodynamic quantities with respect to equilibrium steps by van't Hoff plot of the proposed mechanism.

    ABSTRACT: The method developed is based on pK(a) values and proton exchange concept, in which ponceau 4R reagent (pK(a) = -2.8) reacts with amoxicillin (pK(a) = 3.39), both of which are colorless solutions in protonated form. On mixing these compounds at suitable conditions, pale red color develops at room temperature. It is predicted that ponceau 4R undergoes proton exchange and forms salt based on number of carboxylate anions in amoxicillin. The formation of ionic solution, by mixing of amoxicillin and ponceau 4R imparts color to the resultant solution. The resultant ionic solution shows maximum absorbance at wavelength, lambda(max) = 509 nm. The method complies with Beer's law at concentration range, 10-50 mu g/ml. The coefficient correlation was 0.999 for the linear curve equation, Y = 0.030x + 0.021. Method detection limit (MDL), limit of, detection (LOD)limit of quantification (LOQ), lower critical limit (LCL), upper critical limit (UCL), signal noise ratio (SNR), t-value, p-value and confidence interval were calculated for the ionic solution of amoxicillin and ponceau 4R. Average recovery of amoxicillin solution was made to 100.6. The method validated is as per International conference on harmonization (ICH) and association of analytical communities (AOAC) guidelines. The method was found to be simple, accurate, and economical. Amoxicillin and its colored ionic solution were testified on RP-HPLC. H-1 NMR spectrum of the drug and the ionic solution formed was also recorded to verify the possible mechanism. The ionic solution was stable up to 12 h.

    ABSTRACT: Some new 4-[(E)-(4-hydroxy-3-methoxybenzenylidine)amino)1-N-(substituted)benzenesulfonamides were synthesized by condensation between aldehyde with different sulphanalamide derivatives. Electrochemical behaviour of 4-RE)-(4-hydroxy-3-methoxybenzenylidine)amino)]-N-(substituted)benzenesulfonamides have been studied in Britton-Robinson buffers of pH 2.5-12.0 at dropping mercury electrode. All benzenesulfonamides gave one electron wave corresponding to the reduction of -C=N- bond at mercury electrode. On the basis of differential pulse polarography, IR, mass and H-1 NMR spectral studies and product identification, a reduction mechanism has been suggested.

    ABSTRACT: A simple, accurate and precise spectrophotometric method was developed by the authors for the determination copper(I) using molybdenum(vi) (ammonium molybdate solution) as a chromogen by molybdenum blue method. During the reaction between copper(I) and ammonium molybdate solution, an instantaneous, stable ink blue color (molybdenum blue) was developed, which showed a wavelength of maximum absorption at 834.8 nm. As a result of such experiments which showed remarkable sensitivity, ammonium molybdate was also used as a reagent for the spot test of copper(I). Beer's law was found to be obeyed up to 1.9798 mg of copper(I) chloride in the solution. Correlation factor was found to be 0.9746. SD and RSD were found to be well within the prescribed limits. The reagent, ammonium molybdate was also used for the photometric determination of copper(I) with good and appreciable results of accuracy. Thus the chromogen molybdenum(VI), can be used for both qualitative and quantitative determination of copper(I) in aqueous/acid media.

    ABSTRACT: Quantitative structure activity relationship (QSAR) study has been performed on the dihydro-pyrazolyl-thiazolinone derivatives. This study is based on modeling the COX-2 inhibitors of dihydro-pyrazolyl-thiazolinone derivatives using topological and physicochemical parameters. It has been demonstrated that steric, electronic and topological parameters along with indicator variables are significantly correlated with activity. The multiple regression analysis revealed that the four-parametric model containing chi(eq) Mv, I-1, I-2 are correlating parameters and best for modeling the activity of the compounds under present study which was able to explain 89.7% of the variance in the data. The QSAR models were tested for their statistical significance and reliability by using leave one out (LOO) cross validation method.

    ABSTRACT: A new chelating ligand [4-methyl-2,6-bis-(pyridin-2-yl-hydrazonomethyl)-phenol] (1) was prepared by the condensation of 2-hydrazinylpyridine with 2,6-diformyl-p-cresol. Compound 1 exhibits weak fluorescence due to intramolecular photoinduced electron transfer (PET). The sensor (1) demonstrates Zn2+-specific emission enhancement due to "PET off" process through a 1 : 1 binding mode with the metal ion. The fluorescence quantum yield of the chemosensor 1 is only 0.020, and it increases more than 14-fold (0.280) in the presence of one equivalent of the zinc ion. Interestingly, the introduction of other metal ions causes the fluorescence intensity to remain either unchanged or weakened except for Cd2+. Ratiometric displacement of Cd2+ ion from the complex by Zn2+ ion supports the formation of more stable sensor-Zn2+ complex over the sensor-Cd2+ complex. The experimental findings have been correlated with theoretical results using B3LYP functional and 6-31G(d,p), LANL2DZ basis set for Cd2+ (2) and Zn2+ (3) complex, respectively, by Density Functional Theory (DFT) method. Moreover, the ability of probe 1 to sense Zn2+ within human melanoma cancer cells has been explored, and the Zn2+-probing process in living cells was reversible. [Mn-2(PHMP)(2)](ClO4)(2) (4) and [Ni-2(PHMP)(H2O)(5)](NO3)(3) (5) have been also synthesized and characterized crystallographically and spectroscopically to understand the ligating behavior of the ligand PHMP.

    ABSTRACT: Synthesis of nickel(II) and copper(II) complexes of three-dimensional tricyclic aza macrocycle 3,7,10,14,15,19,20,24-octaazatricyclo[7.5.5.5(2,8)]tetracosane (OCTC) have been described. Metal-free ligand hydrochloride has also been prepared. Di- and tetrametallic complexes [Ni-2(OCTC)(H2O)(4)]Cl-4 center dot 5H(2)O, [Cu-4(OCTC)(H2O)(8)]Cl-8 center dot 6H(2)O and OCTC center dot 8HCl have been characterized by elemental analyses, conductivity measurements and spectral studies. The thermodynamic stabilities of the complexes, investigated by pH-titration method, are low (10(17.78) and 10(9.28), respectively) for the reactions Cu2+ + A (sic) CuA(2+) and Ni2+ + A (sic) NiA(2+) (A = OCTC) as expected to a non-planar [14]-N-4 ring. Further, structural rearrangement in Ni(2)A(4+) leads to coordination of each nickel(11) ion in different non-planar [12]-N-4 ring cavities with decreased stability constant to 10(6.71) for reaction NiA(2+) + Ni2+ (sic) Ni(2)A(4+). Coordination of additional two cupric ions each in a small cavity of two aza donors (within spherical cavity of the macrocycle), exhibits macrocyclic effect. The enhanced stability (theoretical, but approximate) for reactions CuA(2+) + Cu2+ (sic) Cu(2)A(4+) and Cu(2)A(4+) + Cu2+ (sic) Cu(3)A(6+) over that for open chain ligand 1,3-diaminopropane are >= 10(7.29) and 10(5.55), respectively.

    ABSTRACT: Synthesis and spectroscopic characterization of a mononuclear cobalt(II) compound, [Co(L)](ClO4)(2) (1) [L = N-(1-pyridin-2-yl-phenylidene)-N'-[2-({2-[(1-pyridin-2-ylphenylidene)amino]ethyl}amino)ethyl]ethane-1,2-diamine] (1) is reported. The ligand and cobalt(II) complex were characterized by elemental analysis, FTIR, UV-Vis spectroscopy, H-1 NMR, electron spray ionization (ESI) mass spectrometry and powder X-ray diffraction (PXRD) studies. PXRD studies revealed that 1 crystallizes in P-1 space group with a = 12.5032(3) angstrom, b = 12.4013(3) angstrom and c = 13.162(4) angstrom with unit cell volume is 1617.420 (angstrom)(3). The binding property of the complex with DNA has been investigated using absorption and emission studies. Spectroscopic investigations revealed an intercalative binding mode of 1 with CT-DNA. The activity data show that the cobalt(II) complex has effectively screened bacterial and fungal activity. Structural parameters of the L and 1 has been computed using Density Function Theory (DFT) to understand the molecular geometries of the ligand and its cobalt(II) complex.

    ABSTRACT: Recent reports describing the presence of lead (Pb) in lipsticks have suggested that, under ordinary use, the potential amount of Pb exposure is harmful. This study aims to investigate the content of lead in most frequently used brands of solid lipstick in Sulaimani, Iraq. 30 solid lipstick samples (5 colors from 6 different brands) were selected taken from large cosmetic stores in Sulaimani (Iraq) and lead of them was analyzed by flame atomic absorption spectrometer (AAnalyst 700) with detection limit of 0.05 ppm. The results showed that the concentration of lead in the lipsticks was within the range of 0.45-48.59 mu g/g. There was significant difference between the averages of the lead content in the different brands of the lipsticks. Thus, the continuous use of these cosmetics can increase the absorption of heavy metals, especially Pb, in the body when swallowing lipsticks or through dermal cosmetic absorption. The effects of heavy metals such as lead can be harmful, especially for pregnant women and children. Therefore, effort must be made to inform the users and the general public about the harmful consequences of cosmetics.

    ABSTRACT: A novel 2-nitrobenzaldehyde appended rhodamine-based chemosensor (L) for selective detection of Al3+ ions has been synthesized and characterized by various spectroscopic techniques. The chemosensor L showed high sensitivity towards Al3+ ions without interference from other biologically significant cations examined in CH3CN/H2O (8 : 2, v/v) media by changing the color from colorless to deep pink which was very easily observed by naked eye. While other metal ions, alkali metal and alkaline earth metal cations did not induce such a change. The 1 : 1 binding stoichiometry of the metal complex was established by UV-Vis spectroscopy.

    ABSTRACT: New dithiocarbonates of titanium(IV) and zirconium(IV) corresponding to [(ROCS2)(n)M(C5H5)(2)Cl2-n] (R = 0-, m- or p-CH3C6H4, and 4-Cl-3-CH3C6H3; n = 1 or 2; M = Ti or Zr) have been isolated by the reaction of sodium salt of dithiocarbonates with titanocene or zirconocene dichloride in 1 : 1 and 1 : 2 molar ratio in CHCl3. These have been characterized by elemental analyses, mass, IR and heteronuclear NMR (H-1 and C-13) spectroscopic analyses. Thermal and redox properties of complexes were studied by thermogravimetric analysis and cyclic voltammetry. Based on analytical results, penta- and hexa-coordinate geometries are concluded around the Ti or Zr atom. The antimicrobial test of these complexes has been conducted against the bacteria Klebsiella pneumonia and Enterococcus faciolus and fungus Rhizopus nigricans. The cytotoxic properties of the few ligands and complexes were also measured in vitro using the cultivated human cell lines.
