邻苯二甲酸酯（PAEs）是一类典型的环境激素，对人体健康具有较大的危害。本文采用DK型纳滤膜去除水中微量邻苯二甲酸酯，分析了水中微量邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸正二丁酯(DNBP)和邻苯二甲酸异二丁酯(DIBP)等在DK型纳滤膜表面的吸附行为，考察了4种邻苯二甲酸酯的辛醇/水分配系数(logKow)和相对分子质量(Mw)对其在DK型纳滤膜表面的吸附和膜的截留特性的影响。结果表明Freundlich吸附方程能较好地描述4种邻苯二甲酸酯在DK型纳滤膜表面的动态吸附行为；DK型纳滤膜对水中微量邻苯二甲酸酯的截留特性表现为膜面吸附作用和膜孔筛分效应，吸附平衡后的截留机理取决于膜孔的筛分效应，DK型纳滤膜对DMP、DEP、DNBP、DIBP的截留率分别为55%、78%、96%和96.8%(0.5 MPa，30℃，DMP、DEP、DNBP、DIBP浓度均为300μg/L)，表明DK型纳滤膜能高效去除水中的DNBP和DIBP。
