Abstract: The chemical oxidation degradation(O3/H2O2)of vinyl chloride in water and its kinetics were investigated
at298K and with the pH value of3~11by utilizing the Stopped-flow Spectrometer reactor.A kinetic model for the
degradation of organic pollutants was then established by means of theoretical analysis‚and the reaction kinetic data
were obtained by the regression analysis of experimental data.It is found that the experimental results are in good a-
greement with the theoretical model.

Key words: chemical oxidation, degradation, vinyl chloride, kinetics
