Abstract: | Summary The fundamental characteristics of reverse osmosis on a polymer membrane have been correlated with HPLC experimental conditions
by using the membrane material as a column packing. Twelve formulas were used to calculate the physicochemical characteristics
of the reverse-osmosis separation process and it was found that these characteristics can be determined on the basis of retention
(t
R, VR) and partition coefficient (K) of the solute in HPLC. It seems that HPLC is an effective tool for studying the physicochemical nature of reverse-osmosis
separations and the characteristics of the polymer membrane. |
