Abstract
Sorption of selenium (IV) ions from the solutions of sodium selenite on natural zeolite-containing tuff from the Kholinskoye deposit (Transbaikalia) and on the tuff form modified with protein hydrolysate is investigated. Optimal conditions for tuff modification with protein hydrolysate are chosen. The zone of the safe action of selenium-containing tuff is determined using the test culture Tetrachimena pyriformis.
