摘要
研究了羊毛角蛋白膜的制备及其气体分离性能.以角蛋白膜的CO2渗透速率和CO2相对于CH4的分离系数为指标,考察了制膜液中溶剂氨水的浓度、巯基乙酸和戊二醛的加入量对角蛋白膜的气体透过和分离性能的影响.
Dissolved wool keratin was obtained by means of reduction and dense keratin membranes were prepared thereof. Variation of CO2 permeate rate and CO2/CH4 selectivity of the membranes were investigated against factors including thioglycolic acid, ammonia and glutaraldehyde content in the membrane formation solutions.
