摘要
壳聚糖和膨润土均为吸附剂,利用壳聚糖与膨润土各自的优点,将这两种吸附剂相结合,制成一种新型吸附剂-壳聚糖负载改性膨润土膜,用于吸附铜离子。根据对铜离子的吸附率大小,通过单因素试验,确定了最佳制备实验条件,m(壳聚糖)∶m(膨润土)为3∶2,反应θ为50℃,反应t为10 min。壳聚糖负载改性膨润土膜对铜离子吸附性能最佳。
Chitosan and bentonite are both adsorbents. In this paper,these two adsorbents were combined by using of their own respective advantages, thus, a new adsorbent- chitosan load modified bentonite membrane was prepared for copper ion adsorption. According to the level of copper ion adsorption rate, and by single factor tests, the optimal experimental condition for the preparation was determined as following： mass ratio between chitosan and bentonite was 3： 2,θwas 50 ℃ and t was 10 min.
