Abstract
It was possible to measure the interaction between membrane polymer and solutes by liquid chromatography pached with membrane materials. The results obtained from liquid chromatograhy are useful to consider the mechanism of membrane separation and membrane materials. The retention mechanism in liquid chromatography in these systems, however, are not made clear sufficiently.
In this paper, we described the retention characteristics of inorganic salts and of organic compounds in cellulose acetate-water system, and discussed the retention mechanism and the impacts upon membrane process. Moreover, the other systems of liquid chromatography were also mentioned and the availabillity of liquid chromatography for the study of membrane separation was discussed.
