摘要：

We study the process of oxidation of cyanides, thiocianates, and complex cyanides by a combination of ozone with hydrogen peroxide (peroxone reagent) in model solutions and sorption tails of a gold recovery plant. We establish the kinetic dependences of the oxidation of cyanides, thiocyanates, and complex cyanides by hydrogen peroxide and ozone on the ozone-hydrogen-peroxide ratio, pH value, and the concentration of copper ions. The rate constants of the oxidation of thiocyanate by peroxone are determined and the influence of the concentration of thiocyanate on its oxidation by ozone and hydrogen peroxide is analyzed. On the basis of the accumulated results, we propose a technology of cleaning of cyanide-containing waters (peroxone process) by using a combination of ozone with hydrogen peroxide.
