    ABSTRACT: A facile method was developed for the synthesis of nitrogen-doped porous carbon-gold (NPCAu) hybrid nanocomposite. The NPCAu modified gold electrode has been prepared for the electrochemical determination of ultratrace mercury(II) in drinking water through square wave anodic stripping voltammetry (SWASV). Under optimized conditions, the NPCAu modified electrode shows a sensitive detection to Hg(II) ion present in concentrations of 0.001∼1 μM, with a detection limit of 0.35 nM (S/N=3), which was much lower than the guideline values in drinking water given by the World Health Organization.

    ABSTRACT: Gold-coated magnetic nanoparticles (Au@MNPs) have attracted significant interest in electrochemistry in recent years. This is especially the case with their application as dispersible electrodes where modified Au@MNPs are dispersed into a solution, selectively bind to the analyte of interest and are then brought to an electrode via application of a magnetic field for measurement. This paper characterizes four types of Au@MNPs with different sizes, shapes, and method of synthesis as dispersible electrodes. The Au@MNPs were characterized by transmission electron microscopy and X-ray photoelectron spectroscopy and scanning electron microscopy. In addition, the electrochemical behaviour of Au@MNPs was investigated using cyclic voltammetry. The four sorts of Au@MNPs were evaluated with regards to the three main features required in the dispersible electrodes approach, well-defined morphology, well-defined electrochemistry and fast response to a magnetic field. The Cubic-Au@MNPs, which presents the simplest synthetic route, showed the best electrochemical stability and performance, responding quickly to a magnet and had a well defined shape.

    ABSTRACT: Bisphosphoramidates are known as anticancer, antibacterial, antiviral drugs and enzyme inhibitory agents. These compounds are electroactive and insoluble in aqueous media. Hence, a comprehensive study about the electrochemical properties of them seems very interesting. The oxidative behaviors of some bisphosphoramidates were studied in buffer solution over a wide pH range by cyclic voltammetry and differential pulse voltammetry using spiked carbon paste electrodes. The interaction of these compounds with calf thymus DNA (CT-DNA) showed the ability of these compounds as DNA sensing. The decrease in the anodic peaks of bisphosphoramidates in the presence of DNA was used for the DNA monitoring.

    ABSTRACT: We developed a new electrochemical method for the simultaneous determination of 2-aminophenol (2-AP) and 4-aminophenol (4-AP) based on hollow manganese silicate spheres. The hierarchical hollow structure of manganese silicate submicrometer spheres was formed by the assemblage of numerous nanobubbles, as confirmed by scanning electron microscopy and transmission electron microscopy images. As sensing material for the simultaneous determination of 2-AP and 4-AP for the first time, the electrochemical performances of 2-AP and 4-AP were studied in detail. The detection limits (S/N=3) for 2-AP and 4-AP were as low as 18 and 11 nM, respectively.

    ABSTRACT: Activated sludge was successfully exploited as the medium in the fast ferricyanide-mediated toxicity (FM-TOX) bioassay. The mediated biosensor toxicity assessment using activated sludge greatly simplified the testing process and improved detection sensitivity. The principle of the method is that the respiration of bacteria in the activated sludge is inhibited by the pollutants, and the extent of the inhibition is related to the concentration of toxicants. A series of experimental conditions (activated sludge concentration, incubation time, reaction temperature and pH of the solution) were optimized in order to increase the sensitivity. Different kinds of toxicants and natural water samples were examined under the best conditions and IC50 values of them were obtained respectively. According to the testing results, a toxicity order was given: Hg2+>Zn2+>Cd2+>Pb2+ for heavy metal ions; 3,5-DCP>PA>Methanol for organic toxicants and Machete>DDT for pesticides. The detection limits for those pollutants are lower than the values in the national standard. These results confirmed that this sensor may serve as an early warning device for avoiding environmental pollution and affecting public health.

    ABSTRACT: The catalysts based on 2-aminoethanethiol functionalized graphene oxide (AETGO) with several mono-metallic and bi-metallic nanoparticles such as rod gold (rAuNPs), rod silver (rAgNPs), rod gold-platinum (rAu-Pt NPs) and rod silver-platinum (rAg-Pt NPs) were synthesized. The successful synthesis of nanomaterials was confirmed by various methods. The effective surface area (ESA) of the rAu-Pt NPs/AETGO is 1.44, 1.64 and 2.40 times higher than those of rAg-Pt NPs/AETGO, rAuNPs/AETGO and rAgNPs/AETGO, respectively, under the same amount of Pt. The rAu-Pt NPs/AETGO exhibited a higher peak current for methanol oxidation than those of comparable rAg-Pt NPs/AETGO under the same amount of Pt loading.

    ABSTRACT: Cyclic voltammetric (CV) and differential pulse voltammetric (DPV) measurements were carried out to assess the changes in electrode reactivity in halide determination with a silver nanowire-modified platinum electrode. With DPV, successive voltammograms of the halide solution revealed progressive deterioration of the oxidation currents corresponding to Br− and Cl−, while those of I− increased largely. Comparatively, CV is stable and effective to remove precipitates due to the reduction process, in which, the concentrated effect alleviated and the amount of AgI decreased. CV was consequently suggested to be favorable for halide determination, while playing a role in electrocatalytic activation of the electrode.

    ABSTRACT: The two-abrupt-change coulometric titration was proposed for the analysis of the degree of deacetylation of chitosan. The potential was indicated by an antimony electrode which could sensitively response to the variation of activity of hydrogen ion in the turbid and viscous chitosan solution. Through this new approach, the deficiency of combination pH glass electrode in that medium is successfully overcome. The degree of deacetylation of chitosan was obtained by the difference of electrolysis time between two inflection points in the electrolysis process. The measurement error, which is caused by the residual acid or alkali in the chitosan, could be eliminated. The degree of deacetylation of four chitosan samples were investigated by this new method, which found to be consist with those determined by proton nuclear magnetic resonance (1H NMR). The standard deviations were found to be lower than 0.60 % and the whole experimental process can be completed within 15 min. With merit of simplicity, convenience, quickness, accuracy, the proposed new method would possess extensive practicability in scientific research and industrial production.

    ABSTRACT: Reduced graphene oxide (rGO) nanosheets functionalized with 1,3-di(4-amino-1-pyridinium) propane tetrafluoroborate ionic liquid (DAPPT) was successfully synthesized and fully characterized. DAPPT-rGO nanosheets were coated to a glassy carbon electrode (GCE) surface to immobilize tyrosinase (Tyr). The Tyr-DAPPT-rGO/GCE was characterized with scanning electronic microscopy and electrochemical impedance spectroscopy. The biosensor shows a linear response to bisphenol A (BPA) in the concentration range of 1.0×10−9∼3.8×10−5 mol L−1. The detection limit was calculated to be 3.5×10−10 mol L−1 (S/N=3). The practical application was demonstrated by determining BPA leaching from commercial plastic drinking bottles.

    ABSTRACT: We reported an electrochemical sensor with specificity toward maltol with rapid response and high sensitivity, using graphene oxide (GO)-wrapped amino-functionalized carbon sphere (ACS) hybrids as the conductive channel. The results indicated that a well-organized structure was successfully prepared, based on specific electrostatic attractions between the ACS and the GO nanosheets. Next, a sensitive and selective electrochemical sensor was successfully constructed for the direct detection of maltol by casting a GO-ACS film onto the surface of a glassy carbon electrode. The oxidative peak current increased linearly with the concentration of maltol in the range of 0.1 µM∼0.8 mM using differential pulse voltammetry, and the detection limit was 24 nM with S/N=3.

    ABSTRACT: Pyridoxine is analyzed using square wave voltammetry (SWV) at copper nanoparticles (nano-Cu) modified poly-crystalline gold electrode (nano-Cu/Au). Nano-Cu/Au is fabricated by a potential scan electrodeosition technique. Nano-Cu/Au electrode has been characterized morphologically and electrochemically. The analysis of pyridoxine at nano-Cu/Au electrode is achieved utilizing the quenching of copper voltammetric response due to the complexation with pyridoxine forming an electroinactive complex. Pyridoxine selectively forms complex with copper ions (modifier), but not with Au (underlying substrate) as supported by UV/Vis spectrophotometry. Using SWV the calibration curve for pyridoxine analysis was obtained in the concentration range of 0.3–2.7 µM with high correlation coefficient. The proposed method has been successfully applied for the determination of pyridoxine in two dosage forms.

    ABSTRACT: It was demonstrated that Principal Components Analysis and Principal Components Regression support qualitative and quantitative investigation of three-component synthetic samples containing micromolar concentration of caffeic acid (CA), syringic acid (SA) and vanillic acid (VA), in various proportions. The first, second and third PCs enable modelling of relationships and distinction of objects of different composition. Optimized and validated multivariate calibration models, implemented on the basis of the samples selected with the help of 3-level full factorial design, effectively support simultaneous determination of the considered analytes. Obtained RMSEP was no higher than 0.23 μm for CA, 0.17 μm for SA and 0.21 μm for VA, in relation to the concentration of 1.9 to 21.4 μm of each compound. Recovery between 90–108% for considered analytes, determined in synthetic wine solution, was additional verification of calibration model. Application of automatic baseline correction was extensively studied.

    ABSTRACT: Quenching of Ru(bpy)32+ electrochemiluminescence (ECL) by Cl−, Br−, and I− ions was studied as a function of halide concentration in a bipolar electrochemical cell. All of the halides investigated showed similar qualitative behavior: above a critical concentration, ECL intensity was found to decrease linearly as the halide ion concentration was increased, due to dynamic quenching of Ru(bpy)32+ ECL. Stern-Volmer slopes (KSV) of 0.111±0.003, 4.2±0.3, and 6.2±0.3 mM−1 were measured for Cl−, Br− and I−, respectively. The magnitude of KSV correlates with halide ion oxidation potential, consistent with an electron transfer quenching mechanism. Using the bipolar platform described herein, aqueous, halide-containing solutions could be quantified rapidly using the sequential standard addition method. The lower detection limit is determined by a complex mechanism involving the competitive electrooxidation of halide ions and the ECL co-reactants, as well as the passivation of the surface of the bipolar electrode, and was found to be 0.20±0.01, 0.08±0.01 and 10±1 mM, respectively, for I−, Br−, and Cl−. The performance of the bipolar ECL quenching assay is comparable to previously published fluorescence quenching methods for the determination of halide ions, while being much simpler and less expensive to implement.

    ABSTRACT: Caffeine (CAF) in aqueous solutions was extracted into acetonitrile (MeCN) using solid phase extraction (SPE). The voltammetric detection of CAF in MeCN was performed in a microcentrifuge tube after SPE in order to minimise the required amount of MeCN and reagents used during the analysis. The voltammetric determination of CAF from a range of beverages extracted into MeCN was in good agreement with the results obtained from HPLC measurements on the same samples. The SPE-coupled voltammetric method gave more accurate results than those obtained via the direct voltammetric detection of CAF in real beverage samples.

    ABSTRACT: The sensitive detection of honokiol was performed using a graphene nanosheets-based electrochemical sensor by cyclic voltammogram and a differential pulse anodic stripping voltammogram. Several important parameters such as deposition cycle of reduced graphene oxide, the acidity of the running buffer, accumulation potential and accumulation time were investigated to acquire the optimum conditions. The sensor was further applied to quantification of honokiol in the concentration range from 0.005 to 10 µM with a low detection limit of 1.7 nM. Finally, the sensor successfully determined the content of honokiol in Ageratum Liquid with a satisfied recovery of 98.2 %∼99.1 %.

    ABSTRACT: A simple but sensitive electrochemical method was proposed for simultaneous determination of paracetamol (PCT) and diclofenac (DCF) based on poly(diallyldimethylammonium chloride) (PDDA) functionalized graphene (GR). Although GR enhanced the electro-oxidation peak currents of PCT and DCF, the peak potential difference between two drugs was reduced. By contrast, PDDA-GR greatly increased the electrochemical currents of both analytes while provided well-separated peak potentials. Thus, the voltammetric behavior and simultaneous electrochemical determination of PCT and DCF were investigated on PDDA-GR. The applicability of the proposed method was verified when it was applied in determination of PCT and DCF in pharmaceuticals and lake water.
