Zyma S. Reversed-phase high-performance liquid chromatography of pyrrolidine- and diethyldithiocarbamate complexes and its application in analysis of waters and foodstuff

The thesis contains the results of investigation of chromatographic behavior of pyrrolidine- and diethyldithiocarbamates of As(III), Cd(ІІ), Co(ІІI), Cu(ІІ), Hg(ІІ), Ni(ІІ), Pb(ІІ) and Zn(ІІ) in RP HPLC. The influence of mobile phase composition on retention of these complexes was studied. The conditions of simultaneous chromatographic determination of Cd, Co, Cu, Hg, Ni, Pb, Zn as diethyldithiocarbamates were optimizated. Uniformed method of simultaneous determination of Cd, Co, Cu, Hg, Ni, Pb, Zn and method of As(III, V) determination in natural and drinking waters by RP HPLC were presented. RP HPLC was offered to use for simultaneous determination of a Cd, Co, Cu, Hg, Ni, Pb and Zn in foodstuff. Express-metod of determination of these elements in mayonnaises of "Torchyn-product" Trade Mark after ultrasonic sample preparation stage was developed.
