| 摘 要： | 烷基酚聚氧乙烯醚(APEOn)是一类重要的非离子表面活性剂,由于其生物代谢产物被证实具有较大的毒性,因此引起人们广泛关注.本文使用两种不同的大孔吸附树脂XAD-4、NDA-804对APEOn类物质NP10进行吸附,该技术可为使用大孔吸附树脂去除此类污染物提供理论依据.研究结果表明:XAD-4、NDA-804对NP10都有较好的吸附效果,温度对吸附有较大的影响,升高温度吸附量增大.NDA-804对NP10的吸附效果要好于XAD-4,这与它的化学特性以及孔结构有关.NP1O在两种树脂上的吸附都能用Langmuir吸附等温线方程很好的拟合,表明属于单层分子吸附.吸附热力学参数计算结果表明,XAD-4、NDA-804对NP10的吸附过程是吸热和自发的.吸附动力学拟合结果表明,NP10在XAD-4、NDA-804上的吸附都符合假二级反应动力学.

| Abstract: | Alkylphenol ethoxylates(APEOn) are one of important nonionic surfactants. Recently,the fate and effects of APEOn in the environment have received considerable attention because their bio-degradation products have been proved to have estrogen-mimicking effects to nature receptor. In this paper,two macroporous resins,XAD-4 and NDA-804,were used to adsorb APEOn(NP10) from aqueous solution. This study can provide valuable knowledge about effective removal of aqueous APEOn using macroporous resins. The results s... |
