VERMICULITE SORBENT FOR WATER PURIFICATION FROM HEAVY METAL IONS
Abstract
This article presents the results of the studies established optimal conditions for the release of copper ions from an aqueous solution in a static mode on a vermiculite sorbent. Sorption should be carried out in the pH range 4-7. The maximum sorption capacity of natural vermiculite in relation to ions of copper (II) is 1,024 mmol/g. it is Shown that the exfoliated vermiculite has a low exchange capacity compared to the natural vermiculite.
