Svinarenko T. Metalsubstituted heteropoly complexes of phosphorus and gallium as analytical forms and reagents in analysis

The objects of investigation are reactions of formation of metalsubstituted heteropoly complexes (HPC) GuanPZMo11O40, (where X - central atom, Z - ion of deputy-metal, М - atom of ligand sphere) and reactions with reducing agents and substances which capability to reaction of complexation with deputy-metal. The purpose is devoted to the development of the new opportunities of applying metalsubstituted heteropoly complexes of Phosphorus and Gallium as analytical forms and reagents. Меthods: chemical analysis, visual, IR-, 31Р and 71Ga NMR-spectroscopy, colorimetric, X-ray fluorescent. Results: the methods of the synthesis of new analytical reagents - guanidinium salts of metalsubstituted HPC GuanPZMo11O40, where Z = Ti(IV), Bi(III), Sb(III) - were developed; principal stages in the reaction between 12-molybdophosphate and ascorbic acid (AsA) proceeded in the presence of Bi(III) ions were clarified; highly selective and fast method for the determination of AsA, cysteine, hydrogen peroxide, monoperoxophtalic acid and Phosphorus has been developed. Volume of providing: introduce in chemical laboratory of Pology cmemical plant "Coagulant". Region of utilization - analytical chemistry.
