Chemical Reactions in Treatment with Pulsed Electric Discharges of an Active Metallic Charge in a Solution of a Chromium(VI) Salt

摘要

Effect of pulsed electric discharges on aqueous solutions of chromium(VI) in a reactor with an aluminum or iron charge was studied. A mechanism of the occurring processes was suggested. Changes in the pH values of the aqueous solutions of chromium(VI) and the composition and yield of the products formed were determined. The possibility of water treatment to remove chromium by this method was demonstrated.
