摘　　要：以聚己内酰胺(PA-6)膜材料作为高效液相色谱(HPLC)柱填料,以小分子量化合物为探针分子,用HPLC法测定探针分子的保留时间(tR)、保留体积(VR)和平衡分配系数(K/).利用HPLC实验数据研究PA-6膜材料的界面性能.实验结果表明:PA-6膜材料的亲水性较好,对不离解极性有机性的分离效果更好.The High Performance Liquid Chromatography （HPLC） method was employed with polyamide-6 （PA-6 ） membrane material as Column packing, and small molecular weight compound as probe molecule was employed to measure the retention time （tR）, the retention volume （VR） and equilibrium distribution coefficient （K）. The interfacial properties of PA-6 membrane materials were characterized by HPLC experiment data. Experimental results showed that PA-6 was better in the hydrophilicity and the separation efficiency for non -dissociable polar organic solute.
