The present study attempted to investigate the applicability of
an EC method in the treatment of aqueous solutions containing
hexavalent chromium by using a fixed bed electrochemical
batch reactor. This design offers high anode surface area
(491 cm2
), very low current, voltage and IR drop so the hexavalent
chromium concentrations decrease at short coagulation
time. The influence of variables such as initial metal ion
concentration, applied current, electrolyte [sodium chloride
and sodium sulfate] concentration and initial pH of the solution
was investigated.
