膜与溶质相互作用的测定方法的研究及作用

Study and Use on Determining Method for Solute-Membrane Interaction

本文以液相色谱实验及理论为依据,提出了判据△_t(=V_R(1)—V_R(D_2o)).根据△_t的大小可判定膜与溶质相互作用类型及强度,并结合分离实验,说明了这种相互作用与分离率f 的关来.依判据△_t 与f 的关系,可进行膜材料选择,膜性能预测,膜材料的定向合成等三方面的工作.

According to liquid chromatography experiments and theory,the criterion (Δ_1=V_(R(1))-V_(R(CD_2D)))has been advanced in this paper.On basis of the Δ_1,the type and strength of solute-membrane interac-tion may be determined.Comparing the Δ_1 with solute separation(f) obtained in reverse osmosis(RO)membrane separation experiments,the relationship between f and solutemenbrane interaction has beenverified.In the light of the relationship between f and Δ_1,the following subjects can be finished:(1)forecasting solute separation(2)selecting membrane material (3)“tailor-making” membrane materi-al.
