| 摘 要： | 论文采用批量平衡法,研究两种土壤对于内分泌干扰物双酚A和类固醇（E1、E2、EE2、E3）的吸附特征,并探讨了温度和离子强度对吸附的影响。结果表明,五种物质在两种土壤中的吸附存在快速吸附和缓慢平衡的过程,Freundlich方程能够较好的拟合土壤对水中低浓度内分泌干扰物双酚A和类固醇的吸附等温线。土壤对五种物质的吸附是放热过程,温度升高会降低土壤的吸附容量。随着离子强度的增加,吸附容量增大。

| Abstract: | The adsorption performance experiments of two kinds of soils on endocrine disrupting chemicals（EDCs） bisphenol-A（BPA） and steroids（E1、E2、EE2、E3） were studied through batch equilibrium methods,influence of temperature and ion strength on adsorption was also investigated.The results show that a fast adsorption and slow balance take place in the adsorption process,the adsorption behaviors of selected EDCs on soils may be well described by Freundlich model.The adsorption of the tested soils on BPA and steroids is an exothermic process;the adsorption capacity of soils on BPA and steroids decreases as temperature rises and increases with ionic strength increasing. |
