摘要
采用苯基乙烯基亚砜对纤维素膜进行化学改性,制备了亚砜基纤维素膜,并测试了其SO2气体渗透性能;观察到该膜对SO2的渗透系数随气体压力增大而减小,符合双吸附-双迁移模型.
A cellulose membrane modified by phenyl vinyl sulfoxide was prepared. The SO_2 permeability of the modified-cellulose membrane was studied, and it is found that the SO_2 permeability of the membrane decreases with the increasing of SO_2 pressure, which is followed the dual sorption and diffusion mechanism.
