| 摘 要： | 通过试验寻求γ-PGA/CS复合膜中γ-聚谷氨酸与壳聚糖的最佳合成比例,并对复合膜吸附性、吸水性和保水性进行研究。结果发现添加了γ-聚谷氨酸的复合膜,金属离子吸附力、吸水力和保水力皆有所增加,而聚谷氨酸和壳聚糖的比例为1:6的复合膜体现出更为明显优势,具有较强的保水性、吸水性和金属离子吸附能力。

| Abstract: | To find the optimal ratio of poly glutamic acid and chitosan in y-PGA/CS (y-poly glutamicacid/chitosan) composite membrane,and its adsorption,water absorption and water retention.Results:The adsorption capacity,water absorption capacity and water retention capacity ofγ,-PGA-added composite membrane,were increased.And the composite membrane with a γ,-PGA and CS ratio of 1 to 6 shows a more obvious advantage,it has a stronger water retention,water absorption and metal ion adsorption capacity. |
