Abstract
The study was undertaken to investigate the effects of ZnCl$_2$ in polysulfone(PSf)/N-methylpyrrolidone(NMP) on the structure and performance of its membrane. The effects of additives on the performances of membranes have been studied. It has been shown that some low molecular weight additives in polysulfone(PSf) casting solutions have effects on the performances of membranes cast from these solutions. It had been reported that ZnCl$_2$, as the additives-in PSf casting solution, decreases water permeability and increases the rejection rate of its membrane.
