Thermodynamic computer simulation of heterogeneous multicomponent systems containing arsenic(III), arsenic(V), and calcium chlorides, hydrochloric acid, nitric acid, hydrogen peroxide, and oxygen is carried out for temperatures of 25–100‡C. The solute state of arsenic is found to influence the fugacities of arsenic trichloride and hydrogen chloride. Arsenic(III) oxidation in chloride solutions and distillation of arsenic-containing solutions in the presence of oxidants are studied experimentally to determine conditions for a rapid and virtually complete oxidation of arsenic in chloride solutions by nitric acid, ammonium nitrate, and hydrogen peroxide.
