以醋酸纤维素(CA-398)膜材料为填料,用HPLC法测定无机溶质(如氯化钠,硫酸镁)和多官能团的有机溶质(如糖等)的保留体积V_R’,平衡分配系数K_A’。由HPLC实验数据来确定聚合物膜材料界面参数。
The retention volume V_R ’of inorganic solutes (such as sodium chloride and magnesium sulfate) and polyfunctional organic solutes (such as sugar) were determined by HPLC using cellulose acetate (CA-398) membrane as filler. The equilibrium partition coefficient K_A ’. The experimental data of HPLC were used to determine the interface parameters of polymer membrane materials.
