- Аннотация: The solubility of ozone and the kinetics of its decomposition and interaction with chloride ions in a 1 M aqueous solution of NaCl at 20 degrees C and pH 8.4-10.8 were studied. The ratio between the concentration of O(3) in solution and the gas phase was found to be 0.16 at pH 8.4-9.8. The concentration of dissolved ozone decreased sharply as pH increased to 10.8 because of a substantial increase in the rate of its decomposition. It was observed for the first time that the interaction of O(3) with Cl(-) in alkaline media resulted in the formation of chlorate ions. The dependence of the rate of formation of ClO(3)(-) on pH was determined; its maximum value was found to be 9.6 x 10(-6) mol l(-1) min(-1) at pH 10.0 and the concentration of ozone at the entrance of the reactor 30.0 g/m(3). A spectrophotometric method for the determination of chlorate ions (concentrations 1 x 10(-5) - 3 x 10(-4) M) in aqueous solutions was suggested.
