Abstract In the in-situ chemical oxidation remediation of groundwater by organic contamination, there are common problems such as excessive use of oxidants, rebound of pollutants and secondary pollutions. Aniline (AN) was the characteristic pollutant, activated persulfate (PS) was used as the oxidant, and stearic acid was used as the cementing agent to prepare sodium and ferrous sulfate (FeSO₄) acting as a permeable reaction barrier (PS-FeSO₄-PRB). The effects of slow-release capsules components and groundwater flow rate on the release of active substances in PRB and the removal of AN were examined. The results showed that when the active substance/stearic acid in the slow-release capsule was 1/2 and the flow rate of groundwater was 0.1mL/min, the cumulative release rates of PS and Fe²⁺ in the PRB after 48h were 43.18% and 14.98% respectively. With a FeSO₄/PS ratio of 1/9 in PRB, the cumulative removal rate of AN and TOC was 95.37% and 57.07% respectively. A sand column was used to simulate the AN-contaminated groundwater and the remediation efficiencies of two different compared treatments : direct injection of PS and FeSO₄, and construction of PS-FeSO₄-PRB, within 4 days, the cumulative removal rates of AN were respectively 35.22% and 69.74%; the cumulative removal rates of TOC were 15.83% and 14.88% respectively. The remediation efficiency of PS-FeSO₄-PRB was significantly higher than that of direct injection treatment. GC/MS analysis showed that p-benzoquinone, azobenzene and long-chain alkanes were produced after treatment, resulting in low mineralization rate of AN. The continuous pH value and Eh records showed that the redox property and acid-base property of the reaction system of PS-FeSO₄-PRB treatment kept relatively stable. Compared with the direct injection of oxidizing agent, PRB treatment based on the slow-release PS and FeSO₄ capsules showed the lower acute toxicity and the lower secondary contamination risk in groundwater.
