Natural sorbent and catalyst to remove arsenic from natural and waste waters

The authors analyze potential of brucite and black manganese in arsenic removal from aqueous environment. It is found that thermally modified brucite is highly affine to trivalent and pentavalent arsenic, and catalytic oxidation of arsenites up to arsenates is possible on the contact with black mang...

Zusammenfassung:	The authors analyze potential of brucite and black manganese in arsenic removal from aqueous environment. It is found that thermally modified brucite is highly affine to trivalent and pentavalent arsenic, and catalytic oxidation of arsenites up to arsenates is possible on the contact with black manganese during filtration. The test results can be useful in developing the sorption-catalytic approach to arsenic removal from natural and waste waters with the help of natural mineral materials.
