The degradation of atrazine by H2O2 photocatalysis was studied using TiO2(Fe/TIO-R)as photocatalyst and atrazine as model pollutant.The results indicated that atrazine could be degraded by H2O2 photocatalysis with Fe/TIO-R under visible irradiation.The degradation ratio could be 96%after 60 min reaction.which Was obviously higher than the combination of the individual effects of rutile Ti02 and Fe2 03.The fluorescence spectrum analysis for the reaction system indicated that the degradation of atrazine depended on the formation and participation of hydroxyl free radical(·OH)in the system.%以负载Fe(Ⅲ)的金红石型TiO2(Fe/TIO-R)为光催化剂,以内分泌干扰物阿特拉津作模型污染物,研究了Fe/TIO-R可见光催化H2O2降解阿特拉津的反应特性.结果表明,Fe/TIO-R能可见光催化H2O2降解阿特拉津,反应60 min,阿特拉津的降解率达96％,明显大于金红石型TiO2与Fe2O3单独作用的加和；通过对反应体系的荧光光谱分析显示,阿特拉津的降解涉及羟基自由基(·OH)的产生与参与.
