| 摘 要： | 为了解表面活性剂溶液对憎水性污染物增溶过程的影响因素，研究六氯乙烷在Ｔｗｅｅｎ２０溶液中的增溶动力学过程，建立了六氯乙烷在表面活性剂溶液中增溶的传质模型．模型表明当六氯乙烷总表面积固定时，其溶解速率同六氯乙烷在表面活性剂溶液中的表观溶解度和表观传质系数呈正相关．发现六氯乙烷在表面活性剂溶液中的表观传质系数和纯水中的相比降低了，但由于表面活性剂对六氯乙烷的增溶作用导致其溶解速率总体上是提高的

| Abstract: | The kinetics of hexachloroethane dissolution into surfactant solution was studied and a mathematical model describing the mass transfer process was developed. The model indicated that dissolution rate is directly proportional to observed solubility and observed mass coefficient of hexachloroethane in surfactant solution. It was found that surfactant decreases the observed mass transfer coefficient relative to water alone, however, the influence of surfactant on hexachloroethmane solubilization results in an overall increase in hexachloroethane dissolution rate. |

| Keywords: | surfactant solubilization mass transfer coefficient hydrophobic pollutants. |
