FEATURES OF SORPTION OF SODIUM ARSENITE BY SOILS IN THE UDMURT REPUBLIC
The sorption of sodium arsenite by different types of soil typical of the region is investigated. It is established that the sorption of arsenic in the form of arsenite ion differs from the sorption of heavy metal cathions such as copper (2+) and cadmium (2+) due to different adsorption mechanisms of soil contaminants in anionic and cationic forms.
