Ion flux

Generally, a membrane is a composite and is made by forming a skin layer on a support. Then, the support will also affect the rejection, since the support affects the ion flux. In practical terms, however, the effect of support on membrane performances is almost always neglected. In this paper, the

An equation of rejection curve was derived for a membrane system where the membrane charge strongly affected the partition of ions into the membrane surface. The equation predicted that the rejection varied linearly with the inverse of the volume flow. The equation was applied to the experimental da
