摘　　要：选择活性红MS和非离子表面活性剂OP-10为目标污染物,在草酸铁络合物/过氧化氢光催化体系中重点考察了在不同OP-10浓度、辐射光强度以及无机盐存在的条件下活性红MS的光催化氧化降解反应.研究结果表明,低浓度的OP-10对活性红MS的光催化降解反应的抑制作用明显,但是随其浓度的升高,抑制作用逐渐减弱;OP-10对活性红MS光催化反应的影响作用并未因辐射光强度的变化和硫酸钠存在而发生明显变化.Photocatalytic degradation of Reactive Red MS with ferrous （III）-oxalate complex/H202 in water is conducted in the presence of nonionlc surfactant OP-10. A few factors affecting degradation of Reactive Red MS such as OP-10 concentration, irradiation intensity and inorganic salt are investigated. The results show that the degradation of Reactive Red MS is significantly limited by low concentration of OP-10, but the limitation is gradually reduced with increasing concentration of OP-10. Moreover, the influence of OP-10 on the degradation of Reactive Red MS is not remarkably depended on irradiation intensity and inorganic salt in water.
