METHOD OF EXTRACTION OF METAL IONS FROM AQUEOUS SOLUTIONS Russian patent published in 2007 - IPC B01J20/02 C02F1/28 

Abstract RU 2297275 C2

FIELD: environment control; sorption technology for cleaning aqueous solutions from metal ions.

SUBSTANCE: proposed method is carried out by sorption of metal ions with the use of inorganic silicate sorbent of the following composition: M2SiO4 or M3SiO5, where M is Mg, Ca, Sr, Ba; process is performed at pH from 2 to 14. Proposed method makes it possible to harden and immobilize sorption product in cement composition.

EFFECT: enhanced efficiency.
