METHOD FOR DETERMINATION OF INORGANIC SELENIUM IN WATER MEDIUM

摘要

The invention relates to means of analytical chemistry for analysis of drinking-surface and earth waters polluted with selenium, in control of processes of water purification, ecological monitoring of natural and sewage waters and in scientific investigations. Method for determination of inorganic selenium in different valence forms is in previous concentration of selenium on anion-exchange tar with following fractioning of different valence forms with chloride acid with respective concentration and following determination with fluorescent method. The invention provides increase of effectiveness of determination of selenium in water medium and repeatability of results of analysis.
