PAN based-based copolymer membranes for dehydration of water/pyridine mixture

물/피리딘 혼합물 분리용 PAN계 공중합막

1. Introduction : We have researched to separate water effectively from aqueous pyridine solution. In our previous papers, we have proposed new separation mechanism, in-situ complex, which is different from solution-diffusion and accelerated transport by hydrogen bonding. We have adopted in-situ complex mechanism to membranes containing phosphoric acids as well as acrylic acid and sulfonic acid in copolymer for dehydration of pyridine.
