摘　　要：利用O3／H2O2体系降解内分泌干扰物类除草剂西草净，西草净质量浓度为2mg／L，过氧化氢与臭氧摩尔比为0．7，臭氧质量浓度为6．8mg／L，室温（23℃），pH值为5—6的条件下，西草净的去除率最高可达92．9％，结果说明O3／H2O2体系氧化西草净的反应条件温和，易于工程应用。The endocrine disrupter Simetryne was oxidized by O3/H2O2 and the reactive products were analyzed by chromatography to assess the degradation efficiency of Simetryne. The Simetryne of 2 mg/L initial content was removed about 92.9% by O3/H2O2 system when the dosage of O3 was 6.8mg/L, the molar ratio of H2O2 to O3 was 0.7, the temperature was 23 ℃ and pH was 5 -6. The results indicate that Simetryne can be conveniently removed by O3/H2O2 system in ordinary reactive condition.
