- 摘要:
- 采用纤维素与壳聚糖复合的方法，以戊二醛为交联剂制备了一种具有 Cu 2+ 印迹的纤维素 / 壳聚糖复合微球，考察了制备过程中纤维素种类，纤维素与壳聚糖质量比、戊二醛用量、交联时间、交联温度及溶液 pH 对吸附铜（ Ⅱ ）的影响，并用扫描电镜（ SEM ）和傅里叶红外光谱（ FTIR ）对复合微球进行表征。结果表明，当壳聚糖与羧甲基纤维素质量比为 9 ∶ 1 ，戊二醛用量 0.7 mL ，交联温度 35 ℃ ，交联时间 80 min ，溶液 pH 为 5.23 时，复合微球对铜（ Ⅱ ）有较好的吸附性能，且具有良好的选择吸附能力。
- Abstract:
- ： The cellulose/chitosan composite microspheres were prepared by compounding cellulose and chitosan using glutaraldehyde as crosslinking agent. The effects of cellulose types ， mass ratio of cellulose to chitosan ， glutaraldehyde dosage ， crosslinking time ， crosslinking temperature and solution acidity on the adsorption of copper （ Ⅱ ） by composite microspheres were investigated. The adsorbent was characterized by scanning electron microscope （ SEM ） and Fourier transform infrared spectroscopy （ FTIR ） . The results show that when the mass ratio of chitosan to carboxymethyl cellulose is 9 ∶ 1 ， the glutaraldehyde dosage is 0.7 mL ， the crosslinking temperature is 35 ℃ ， the crosslinking time is 80 min and pH is 5.23 ， cellulose/chitosan composite microspheres has good adsorption performance for copper （ Ⅱ ） and good selective adsorption capacity.
