摘要

The low ultrafiltration(UF)membranes performances depend mainly on the nature of the interactions between the solutes and the membrane material.This paper reports the filtration tests of different salts:CH3COONa,Na2HPO4 and NaF by means of a TiO2-ZnAl2O4 membrane prepared by sol-gel route deposed on a moroccan clay support.The measured rejections depend at once on the pH,on ionic strength of the solution;their interpretation needs to precise the exact speciation of the filtered species.
