中文摘要：

以125W高压汞灯为光源,在低温（-12—-14℃）条件下,研究了紫外光作用下冰相中对氯苯酚（4-CP）光转化反应.考察了各种因素对冰相中4-CP光转化的影响以及冰相中4-CP光转化的动力学和机理.结果表明,4-CP初始浓度,pH值和光强对冰相中4-CP光转化都有较大影响.在180min内,4-CP和TOC的转化率分别达到了96%和30%,在本实验条件下,4-CP在冰相中光转化的产物和机理与其在溶液中有所不同.

英文摘要：

While the UV lamp（125W）was lamp-house and the p-chlorophenol（4-CP）in ice was the object of this research. All kinds of influencing factors and the kinetics and mechanism of the photoconversion reaction was investigated under the temperature of-12—-14℃. According to the results, the initial concentration of the 4-CP,the initial pH and the intensity of the light had serious effects on the conversion of the 4-CP. The disposal rates of 4-CP and TOC in ice reached 96% and 30% within 180min. At this condition, the mechanism and photoproducts of 4-CP photolysis in ice was a little different from that in the solution.
