Abstract

The continuous removal of toxic hexavalent chromium from contaminated solutions by means of a graphite felt based electrochemical column was studied. The process is based on an in situ generation of appropriate pH gradients which allows both rapid reduction to Cr³⁺ and its precipitation within the electrode bed. Conditions for the attainment of low (<25 p.p.b.) effluent concentrations as well as longitudinal concentration distribution of the precipitate and maximum loading capacities are presented. Treatment schemes involving two separate columns or a dual function column are also discussed.
