摘要：
The oxidation of arsenious acid with ozone in aqueous solutions and sulfuric acid solutions was investigated. In this work, six variables were considered as those affecting the rate of oxidation: (1) rotation speed, (2) initial arsenious acid concentration, (3) arsenic acid concentration, (4) partial pressure of ozone, (5) pH and (6) temperature. Zero order kinetics with respect to arsenious acid and arsenic acid concentrations and first order kinetics with respect to partial pressure of ozone were observed. Gaseous ozone dissolves rapidly in the aqueous solution and equilibrium between the gas and liquid is established.
