Hexavalenl chorrnium in the effluent from plating/metal fin~shing industries llas been known to be the major toxic pollutant, which necessitates removal-ot the same as a measure of environmental pollul~on control. Treatment of such effluent has been mainly or~entedto wards reduct~ono f cr6' lo cr3+f ollowed by removal of the same by prec~pitat~oTnh.e present paper deals w ~ t hth e investtgatrons carried out in a packed bed reactor of flow-by confi ?u ration on electrochemical reduct~ono f ~ r "lo ~ r "st arting w~tha n in~tiacl oncentration of 200 ppm Cr + and at pH 1.5 and f l o ~ra tes rangrng lrom 6 lo 15 IVhr. It has been observed that 100% conversion could be achieved by electrolysis.
