摘　　要：利用UV/H2O2工艺对典型的烷基酚聚氧乙烯醚类物质Triton X-100(TX)进行降解,考察了不同反应条件对降解效果的影响,并且使用分子探针法测定了光解体系中羟基自由基的稳态浓度。以人类雌激素受体重组基因酵母测定其光降解过程中的雌激素效应变化,结果表明雌激素效应并未随着光解过程有较大的变化。A representative alkylphenol ethoxylates Triton X-IO0 （TX） was photodegradated in water by UV/H202 treatment pro- cesses. The photodegradation kinetics of TX and multiple influencing factors were investigated. With nitrobenzene as molecular probe in competitive kinetic experiment, the steady-state concentration of · OH was measured. The estrogenic effect of TX through the photodegradation process was determined by recombinant gene yeast. The result shows estrogenic effect has no significant change through photodegradation process.
