    ABSTRACT: Ammonium ion exchange behavior of synthetic zeolites, i.e., sodalite (SOD), rho zeolite (RHO), Linde type A zeolite (LTA), and faujasite zeolite (FAU), was investigated by changing the initial concentration of ammonium ions and reaction time. Ammonium ion exchange behavior was dependent on the open‐window sizes, the pore structures, and the cation exchange capacities of these zeolites. Regarding sodalite with Na ions (Na‐SOD), ammonium ion exchange did not completely occur at the equilibrium state because the open‐window size is smaller than the diameter of ammonium ions. Regarding RHO with Na and Cs ions (NaCs‐RHO), the larger cations, Cs ion, in the cages obstructed the ion exchange at the initial stage. However, the amount of exchanged ammonium ions gradually increased with increasing reaction time, finally achieving equilibrium. Regarding LTA with Na ions (Na‐LTA), the amount of exchanged ammonium ions decreased with increasing reaction time, and then reached plateau. It indicated that both the ion exchange on the α‐cages and physical adsorption on the β‐cages occurred at the initial stage, which was followed by the equilibrium state of ion exchange on the α‐cages. Regarding FAU with Na ions (Na‐FAU), no dependence on reaction time was observed, because the size of the open‐windows is large enough for ion exchange of ammonium ions. The Na‐FAU, which has the biggest open‐windows among these zeolites, showed the highest exchange capacity for ammonium ions, 3.20 mmol/g.

    ABSTRACT: Di(2-ethylhexyl)phosphoric acid (D(2)EHPA) has the tendency to adsorb at interfaces in an oriented fashion due to the amphiphilic structure. The study of the surface tension shows that the adsorption of D(2)EHPA at interface can lower the surface tension of ethanol solution. The amount of adsorption is affected by the pH and ionic strength of the solution. Being a small surface-active molecule, a monolayer of D(2)EHPA molecules can be immobilized on the surface of nonpolar Amberlite XAD-4 resin by a two-step, organic solvent-nonorganic solvent process. The amount of immobilized D(2)EHPA is as high as 1.02 (mol/kg of resin). The electron spectroscopy for chemical analysis (ESCA) results show that the immobilized D(2)EHPA undergoes reorientation by further exposing the phosphoric acid group to the water phase. Since the hydrophobic alkyl chains of D(2)EHPA physically entangle with the surface polymer chains of Amberlite XAD-4, the immobilized extractant has good stability on the resin surface. This D(2)EHPA-modified Amberlite XAD-4 can be used for the separation of lead and copper ions as an ion-exchange resin. Ion-exchange isotherm experiments show that D(2)EHPA-modified resin has higher Pb ion affinity than Cu ion. This new type of D(2)EHPA-modified resin shows better Ph and Cu ions separation than analogous D(2)EHPA-impregnated resin [extractant-impregnated resin (EIR)] and solvent extraction system. The selective separation results using series contacts of solution mixtures with resins further demonstrated the feasibility of using D(2)EHPA-modified Amberlite XAD-4 resin for the separation of Pb/Cu mixed ion solution. After only six batches of contacts, the relative ion concentration of Cri ion increases from 50% to more than 99%, while the relative ion concentration of Pb ion decreases from 50% to less than 1%. The Cu recovery rate is more than 75%, comparing to 54% in the EIR system.

    ABSTRACT: In this study, ion-exchange resins of the cation exchanger universal (KU)-2 type with functional sulfate groups, a carboxyl-containing cation exchanger of a carboxyl containing cationite (KB) type, and polyampholyte amphoteric carboxyl containing ion exchanger (ANKB)-35 were studied for Ni2+ and Cu2+ ion extraction from water solutions. The high value of the ion-exchange capacity of the ionate KU-2 compared with the complex formation amphoteric ion-exchange resin ANKB appeared to be more suitable for use in wastewater treatment. The wet KU-2-20 resin has larger static ion-exchange capacity than other gel resins. This paper presents a technological circuit and installation for local treatment of rinsing water of nickel plating with subsequent metals utilization. It was found that the gradual accumulation of nickel occurs during multiple solution circulations with a low rate.

    ABSTRACT: The work presents the synthesis of polyaniline functionalized montmorillonite (PANI/MMT) clay composites and evaluation of their performance as an adsorbent for the mitigation of toxic diethyl hexyl phthalate (DEHP) from water. The formation of composite was confirmed by different analytical techniques such as FTIR, zeta potential analysis, XRD, SEM and AFM. The adsorption capacity of PANI/MMT was superior to MMT. DEHP followed partition mechanism on PANI/MMT whereas MMT favored surface adsorption mechanism. The performance of PANI/MMT for DEHP removal was unaffected by the change in pH of solution, change in salinity and hardness contents in aqueous system and consecutive adsorption desorption cycles compared to MMT. Furthermore, both PANI/MMT and MMT exhibited greater adsorption capacities as compared to the previously published work and showed satisfactory performance in real water samples.

    ABSTRACT: Abstract (of the accepted author version posted online by N. Drouiche: 25 Jul 2015.) Many of the complex biological properties of hydroxylapatite HA are related to the multiple exchange capacities inside the HA structure, including formation of vacancies to accommodate ions with other valencies, in particular carbonate ions and alkali and other metal ions of biological importance. We have recently illustrated the possibilities of using HA to remove various textile dyes from industrial waste waters by co-precipitation with HA. Most dyes can be treated efficiently and the HA adsorbent can be regenerated for reuse following thermal treatment in air to burn of the organic materials adsorbed. However important facts point to a situation more complex than simple adsorption. To elucidate the mode of action of HA on the removal of dyes or organic matter in general, we investigated the interactions of alizarinsulfonate ARS with calcium and phosphate ions in solution as a function of pH and dye/mineral fraction. Alizarin or its salt is thus regarded as a model compound for more complex dyes, which led us to investigate the way calcium ions interact simultaneously with phosphate and ARS. We report here the observation of the formation of mixed complexes of the type phosphate-Ca-dye which demonstrate the competition for calcium ions between phosphate and organic ligands. Keywords: hydroxylapatite, alizarinsulfonate, depollution, textile dyes. For the full text, please ask the corresponding author: N. Drouiche

    ABSTRACT: In this study, reactive extraction of glyoxylic acid (0.93 kmol·m−3) using Amberlite-LA2 (0.24 to 1.67 kmol·m−3) in five different alcoholic diluents is performed at 298 K. The extraction ability of Amberlite-LA2 is found to be in the order of isoamylalcohol (IAA) > nonan-1-ol > octan-1-ol > decan-1-ol > dodecanol. Maximum extraction efficiency, 98.92% is obtained at 1.67 kmol·m−3 of Amberlite-LA2 in IAA. The values of stoichiometric coefficient (m), overall equilibrium constant (KE) and individual constants (K11, K21 and K12) are estimated. The effect of diluent on KD is also quantified by applying LSER model using solvatochromic parameters of diluents.

    ABSTRACT: CFD simulations of single-phase flow in a pulsed sieve plate column are presented. Several options to predict axial dispersion in this computationally challenging equipment are evaluated. The evaluation involves comparison of the two possible approaches of 2D representation of the 3D geometry, comparison of a direct approach with a new approach called as the snapshot approach and comparison of predictions for the computational domain consisting of actual number of plates and the computational domain consisting of reduced number of plates. A computational approach is finally prescribed and validated for quick estimate of axial dispersion in single-phase flow.

    ABSTRACT: This article presents two prototypes of laboratory magnetic separators that generate high gradient magnetic fields. Such a field is created in a separation cell via steel wool. The efficiency of separators was tested on a water suspension containing weakly magnetic Fe2O3 nano/microparticles, prepared in three size fractions in a size range of 60 nm – 10 μm. The separation process was evaluated via optical transmittance of the suspension before and after sequential separation processes. Repeated separations on the same sample exhibit an asymptotic trend that results in the conclusion that it is not possible to trap all solid content. According to the decrease of solid particles concentrations during cyclic separation we set the efficiency of the process. It is maximally 46% for fine fraction, 65% for medium fraction and 40% for coarse fraction, after infinity separation cycles.

    ABSTRACT: The metal ion-binding properties of two 27-membered macrocycles with N2S5O2 donor atoms 1 and 2 were investigated using solvent extraction experiments. In order to explain complexation behavior of macrocycles, extraction of ions in the interfacial region of liquid-liquid phase was modeled by Langmuir adsorption isotherm. The macrocycles 1 and 2 extracted Ag+ metal ion up to 95% to the dichloromethane and chloroform phase effectively. The Ag+ ion adsorption capacities of macrocycles 1 and 2 were obtained as 75% and 98% at 20 oC, respectively.
