壳聚糖可用来进行醇水分离,但用于氧氮分离尚未见报道.本文成功地以壳聚糖复合膜分离空气中的氧氮,并且发现干燥膜与在干燥膜表面涂上一层水的“湿膜”之间存在明显的氧氮分离差别. 1实验部分壳聚糖(浙江玉环化工厂)经水洗、酸溶、重沉淀处理后,用稀醋酸溶解,配成一定浓度的
Chitosan can be used for separation of alcohol and water, but it has not been reported for the separation of oxygen and nitrogen.We successfully separated the oxygen and nitrogen in the air with chitosan composite membrane, and found that the dry membrane and the dry membrane surface coated with water Of the “wet film” there is a significant difference between oxygen and nitrogen separation.Experimental part Chitosan (Zhejiang Yuhuan Chemical Plant) after washing, acid-soluble, heavy precipitation, diluted with dilute acetic acid, dubbed a certain concentration
