【摘要】 研究了水体表面微层中酞酸酯化合物（DBP,DEHP）光降解的动力学,指出光催化降解符合一级动力学过程.实验证明:催化剂TiO₂为2g·1^-1,pH为6,并有H₂O₂存在时,是DBP,DEHP光降解的最佳条件;溶解氧增加有利于光降解.实际表面微层水样的光催化降解速率比模拟水样快.更多还原

【Abstract】 Photodegradation dynamics of phthalic ester in water surface microlayer was studied. The result suggests that photodegradation a first-order kinetics. Optimum conditions of photodegradation are: TiO2 is 2g·l-1; pH 6.0 and H2O2 existed. The increasing dissolved oxygen benefits photodegradation . The rate of photodegradation in actual water surface microlayer is faster than that in the simulated system.更多还原
