Abstract

Ultrafiltration membrane has been widely used for several applications due to their high separation capacity, high selectivity, and low operating pressure. In this work, solutes diffusion through polyvinyl alcohol/polyallylamine ultrafiltration membrane was investigated. The membrane was prepared by phase inversion method with glutaraldehyde as crosslinking agent. Meanwhile, NaCl and CaCl2 were used as solutes, either as a single or double solute. The results showed that the increase of polyallylamine concentration led to the increase of membrane swelling degree. For both single and double solutes, diffusion of Na+ and Ca2+ were slightly decreased with the increase of swelling degree. However in double solute diffusion, there was interaction between Na+, Ca2+, and membrane that made Na+ ions moved faster and Ca2+ ions moved slower compared to single solute diffusion. In addition, the increase of solute concentration led to the increase of Na+ diffusion coefficient and the decrease of Ca2+ diffusion coefficient.
