✦ Synopsis
A new in-situ technique was developed for hexavalent chromium removal from sand. Imposition of constant potential gradient acmss the soil matrix through a graphite cathode and iron anode resulted in successful migration of chromate towards the anode. 7be hexavalent chromium ions are reduced to harmless trivalent form by chemical reaction with the anodic dissolution product, Fe2 ' . * 7bis paper won first place in the 1995 AIChE Environmental Dii& sion graduate student research paper competition, 166
