摘要：

研究了NF90膜和NF70膜对纯水、模拟水和河水中邻苯二甲酸二（2-乙基己基）酯（DEHP）的截留和吸附。结果表明：NF90膜能实现对微量DEHP（浓度为100 μg/L）的有效去除，截留率高达95%以上；纳滤初始阶段，DEHP在膜面的吸附作用的较强，吸附率达40%左右。操作压力，pH值，共存有机物、无机物和膜孔径影响DEHP在膜上的吸附，初始浓度的影响不大。

The adsorption and retention of di-2-ethylohexyle phthalate (DEHP), in different water matrices (Milli-Q water, simulated water and river water) by nanofiltration (NF) was examined using two types of nanofiltration membranes (NF90 and NF70). The results showed that DEHP at a concentration of 100 μg/L could be effectively removed by the NF90, and the retention was more than 95%, and the adsorption was about 40% at filtering initial phase. Adsorption of DEHP on membranes was related to operation pressure, pH，coexisting organic and inorganic compounds, and membrane pore size. But no significant effect of DEHP concentration was observed.
