【摘要】 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。更多还原

【Abstract】 The HPLC method with cellulose acetate (CA-388) membrane material as packing isemployed to determine the retention volumes (V’_R and equilibrium distribution coefficient(K’_A) of inorganic solutes (e. g. sodium chloride, magnesium sulfate) and those of organic solutes(e,g. hydrocarbon. Based on the experimental data, the interfacial parameters of the packingmaterial are obtained.更多还原
