中文摘要：

对比研究了腐殖酸（HA）及3种非离子表面活性剂（Tween20,Tween80,TX100）对典型多环芳烃蒽的增溶性,并探讨了离子强度、共存有机物对HA增溶多环芳烃行为的影响.实验结果表明,当表面活性物质浓度大于临界胶束浓度（CMC）时,蒽的表观溶解度与表面活性物质浓度具有良好的线性关系,而且HA与非离子表面活性剂相比,其增溶效果明显优于非离子表面活性剂,增溶顺序为HA〉Tween20〉Tween80〉TX100;同时离子强度及共存有机物对HA增溶蒽的程度均有较大的影响.

英文摘要：

The solubilization of anthracene was characterized by using humic acid in comparison with three typical nonionic surfactants（Tween20, Tween80, TX100） . The influences of inorganic salts and organic cosolutes on solubilization behavior were also investigated. The results showed that not only surfactants in the range of concentration above critical micellar concentration （CMC） but also humic acid could greatly enhance the solubilization of anthracene, and its solubility had the linear relationship with the concentration of surfactants or humic acid. But compared with the nonionic surfactants Tween20, Tween80 and TX100, the solubilization of anthracene were remarkably increased by HA. The solubilization capabilities were as follows HA 〉 Tween20 〉 TweenS0 〉 TX100. And both the ionic strengths of inorganic salts and the organic cosolutes had significant impact on the solubilization of anthracene by HA.
