Assessment of Capacity of Activated Zeolites to Bind Arsenic

Abstract

There was investigated capacity of zeolites absorb arsenic from standardized test solutions. There was demonstrated by means of biotesting methods decreasing of solution Na3AsO4toxicity after interaction with activated zeolites. As adsorbent was used natural zeolite of Sakhaptinsk deposit, Krasnoyarsk Kray (LLC “Etnacom”). Zeolite was activated by V.M. Kan. In other option was taken zeolite, preliminary incinerated and impregnated by humic formulation solution Powhumus at concentration of 1 g/dm3 (or in place of was used Humate-80 at the same concentration). As control was assessed efficiency of arsenic binding by incinerated zeolite without subsequent addition to its humic formulations or other reagents. There was demonstrated that very efficient fom aqueous solution was eliminated zeolite activated by V.M. Kan technique. The same sampling of zeolite had, consequently, maximal sorption capacity, as well as to the maximum extent decreased toxicity of arsenic salts solutions.
