AbstractAbstract
[en] The technique of analysis of natural waters which differ in the mineralization level for determining Mn, Fe, Cu, Zn, As, Tl, Bi, Cd, Ag, In, Pb microimpurities is proposed. To improve the analysis sensitivity preliminary concentration by means of evaporation and extraction of microcomponents by chloroform and extracting them in an organic phase in a form of diethyl-dithiocarbamate complexes have been carried out. Most microimpurities have been determined by means of the X-ray fluorescence analysis method in concentrates which provides sensitivity from 10-3 to 10-2 mg/l. The Tl and Pb content is determined by the gamma activation analysis. The determination sensitivity constitutes 3x10-3 mg/l. The technique may be recommended for serial analysis
