Abstract
The kinetics of electrochemical oxidation of powder and compact PG-50 graphite and also of a carbon-containing stock with ultradispersed dia monds in sulfuric acid solutions of chromic anhydride was studied with the aim to remove carbon-containing admixtures from synthetic diamond micropowders. The possibility of electrochemical regeneration of an o xidizing agent on lead and graphite electrodes was studied by the meth ods of cyclic chronovoltammetry and oxidizing agent curves. Optimal pa rameters of electrolytic oxidation of carbon-containing stock were fou nd.
