Abstract

A dynamic membrane was formed by deposition of colloid particles on a ceramic support. The ZrOCl2 and H2SO4 mixing method was found to be the best method for obtaining regular size particles. The size of the colloid particles increased linearly with the increases of the [H2SO4]/[ZrOCl2] ratio, and ranged from 20 to 200 nm. The dynamic membrane was prepared under a pressure of 0.8 MPa and the particles remained intact and were homogeneously deposited on the ceramic support surface. It is possible to prepare dynamic membranes of molecular weight cut-off greater than 100,000 dalton, and the cut-off increases linearly with the colloid particle size. The dynamic membrane separated BSA from glucose solution effectively.
