中文摘要：

采用磁性离子交换树脂（MIEX）去除水中17α-乙炔基雌二醇（EE2），考察了该过程中腐殖酸（HA）对去除效果的影响。结果表明，HA分子中大量的羧基与EE2分子中的羟基形成氢键，能强化微滤对EE2的去除作用。当MIEX投加量为10mL／L时，其对EE2和HA的去除率分别达到40％～60％和90％以上。虽然MIEX能同时去除EE2和HA，但与MIEX单独处理EE2的对照试验相比，去除率有所下降，这表明HA会抑制MIEX对EE2的去除作用。一方面，HA和EE2在MIEX表面存在竞争吸附作用；另一方面，MIEX对HA的高效去除降低了溶液中游离HA的浓度，削弱了HA对EE2的吸附去除作用。

英文摘要：

Magnetic ion exchange resin （MIEX）was applied to remove 17α -ethinylestradiol （EE2） from water, and the effects of humic acid （ HA ） on investigated. Hydrogen bonds between carboxyl groups in HA EE2 removal efficiency with MIEX were and hydroxyl groups in EE2 could enhance EE2 retention by microfihration. When the dosage of MIEX was 10 ml/L, the removal efficiencies of EE2 and HA were 40% to 60% and over 90%, respectively. Although MIEX could remove both EE2 and HA, the removal efficiency of EE2 with MIEX was decreased compared to the case without HA, which indicated that HA inhibited the removal of EE2 with MIEX. It showed that the competitive adsorption existed between the adsorptions of HA and EE2 with MIEX, on the other hand, the removal of HA with MIEX dramatically reduced free HA concentration in the solution, which impaired the adsorption of HA on EE2.
