摘要：
The influence of the concentration of NaNO3 on the solubility of ozone in water was studied at 20, 30, and 40°C. The solubility coefficients of ozone were calculated, and the Henry constants and Sechenov coefficients determined. The Sechenov coefficients (Kc) were found to decrease insignificantly as the temperature increased. The kinetics of dissolved O3 transformations was analyzed. The decomposition of ozone was described by a pseudofirst-order equation with respect to salt concentration. The rate constant (kc) for the decomposition of ozone in the presence of NaNO3 was found to be 3.5 × 10−4 l mol−1 s−1.
