Abstract

A new in-situ technique was developed for hexavalent chromium removal from sand. Imposition of constant potential gradient across the soil matrix through a graphite cathode and iron anode resulted in successful migration of chromate towards the anode. The hexavalent chromium ions are reduced to harmless trivalent form by chemical reaction with the anodic dissolution product, Fe²⁺.
