Electrochemical reduction of vanadium(V) complex with cupferron (N‐nitroso‐N‐phenylhydroxylamine), VVO(cupf)2OH, has been studied by polarography in wide potential range to verify the catalytic mechanism of electroreduction of coordinated cupferron ligand. Reduction of the complex was studied in the concentration range from 2 ⋅ 10−5 M to 10−3 M. Depending on the process conditions kinetics of catalytic reduction of coordinated cupferron is either controlled by adsorption step or governed by mixed control of diffusion and chemical reaction. Kinetic parameters of the reduction process are reported. Reduction of VVO(cupf)2OH complex is accompanied by adsorption and autoinhibition phenomena. V(II) ion in the surface bound complex of vanadium with cupferron catalyzes reduction of coordinated cupferronate ligands. In 1 mM solutions, the catalytic reduction of coordinated cupferron ligand shifts to more cathodic potentials due to formation of a monolayer of adsorbed vanadium(III)‐cupferron complexes. Reduction kinetics in the presence of tetraalkylammonium salt is consistent with multilayer cooperative adsorption of anionic vanadium(II)‐cupferron complex and tetraalkylammonium cations.

“…It was proven in earlier papers that a simple, cheap and quick way to eliminate the interferences of organic substances in voltammetric determination is previous mixing of the analyzed sample with Amberlite XAD-7 resin [7][8][9][10][11]. Furthermore, in the case of the present procedure the addition to the sample of XAD-7 resin to allow elimination of the above-mentioned interferences was proposed.…”

“…In the case of analysis of environmental samples with organic-rich matrices the preliminary mixing with Amberlite XAD-7 resin was applied before analysis. The mixing with Amberlite XAD-7 resin, gives a superb effect as concerns the elimination of organic matrix interferences [7][8][9][10][11]. In this case, 0.5 g of resin was added to the sample solution with 4.5 cm 3 environmental water, 5 cm 3 triply distilled water, 0.5 cm 3 supporting electrolyte (CH 3 COOH) and proper concentration of 1•10 -4 mol/dm 3 Tytanit solution.…”

<p>The purpose of this work was to determinate the amount of titanium in different environmental water samples spiked with crop biostimulant Tytanit. The measurements were conducted using adsorptive stripping voltammetry (AdSV). The titanium complex with chloranilic acid was accumulated on mercury film silver based electrode (Hg(Ag)FE) at the potential -0.3 V. The analysis of natural water samples enriched with Tytanit, collected in the eastern part ofPolandconfirms that this procedure is fast and essential for the determination of titanium in environmental water samples.</p>

Bismuth has received considerable attention and been widely used in many fields due to its relatively low toxicity and special properties. This paper reviews the physical and chemical characteristics of bismuth, summarizes its applications, and introduces the techniques for the determinations of bismuth. However, the long-term use of bismuth may also bring about some side effects and even toxicity to human body, which was described here as well. In the end, we conclude the current situation and potential future of bismuth in respects of application and determination.
