Study of sorption of Мn2+ ions by natural clinoptilolite
The process of modification of natural clinoptilolite, pre-enriched by the main component, with manganese ions from nitrate solutions as precursors for obtaining manganese(IV) oxide was studied. The value of the sorption capacity of different fractions of clinoptilolite with respect to manganese ions at room temperature was determined, and the sorption rate and rate constants of this process were calculated. The influence of the concentration of manganese nitrate solution on the sorption capacity of certain fractions of zeolite was determined.
