## Abstract Carboxymethyl chitosan (CMCS)/polysulfone (PS) hollow‐fiber composite membranes were prepared through glutaraldehyde (GA) as the crosslinking agent and PS hollow‐fiber ultrafiltration membrane as the support. The permeation and separation characteristics for dehydration of isopropanol w
Pervaporation separation of water-ethanol was carried out with polyion complex membranes based on k-carrageenan. The polyion complex membranes were prepared by the ion complex formation between k-carrageenan (anionic polymer) and poly{ 1,3-bis[4-alkylpyridiniumlpropane bromide } s (cationic polymers
The present study investigated the pervaporation performance of novel hydroxypropylated chitosan (HPCS) membranes to separate water from an aqueous alcohol solution. Hydroxypropylated chitosan was prepared from the reaction of chitosan and propylene oxide. The results show that the separation factor
