Sodium persulfate has been widely used as an oxidant for the remediation of organic-contaminated soil and groundwater. ·SO4- and ·OH- with strong oxidative properties could be produced by sodium persulfate after activation by sodium hydroxide, which could degrade chlorobenzene and other organic substances. In this study, sodium persulfate was chosen as the oxidant, and in-situ chemical oxidation (ISCO) remediation of chlorobenzene contamination in the groundwater of pesticide factories was conducted under the activation of sodium hydroxide, and the removal rate could achieve 95% maximum. Analysed by the results of the Pearson correlation coefficient, the environmentally friendly oxidation product sulphate was negatively correlated with the concentration of chlorobenzene during the ISCO remediation process. However, the remediation effect was also affected by the concentration of pollutants, the nature of the geological horizons, and other factors.
