A positively charged composite NF membrane was prepared by casting quaternized chitosan solution onto PAN ultrafiltration membrane and using mixed anhydride as cross-linking reagent.
Phenol enter or release from film can controlled freely by modulating the potential of PAN films, this characteristic can be used to separate the phenol from the solution.
通过控制PAN薄膜的电位可以方便地控制苯酚的置入与释放，从而达到分离溶液中苯酚的目的。
