摘  要:
[目的]成功制备磁性壳聚糖(MCTS)并进行结构表征,探讨其对Cr(Ⅵ)的吸附能力。[方法]采用红外光谱与扫描电镜对MCTS进行结构表征,考察了Cr(Ⅵ)初始浓度、MCTS投加量、吸附时间、温度对吸附效果的影响。[结果]当Cr(Ⅵ)初始浓度为10 mg/L,MCTS投加量为0.05 g,吸附时间为70 min,水浴温度控制为45℃时,不调节pH,去除率最大可达98.6%。[结论]MCTS已经成功制备,其对Cr(Ⅵ)具有较好的吸附效果。

摘  要:
[Objective] In order to prepare the magnetic chitosan( MCTS) and study its adsorption behavior on Cr( Ⅵ). [Method] The structure of MCTS was characterized by FTIR and SEM. The effect of initial concentration of Cr( Ⅵ),MCTS dosage,adsorption time and temperature was investigated on the Cr( Ⅵ) adsorption. [Result]When the initial concentration was 10 mg/L,the MCTS dosage was 0. 05 g,the adsorption time was 70 min,the bath temperature was 45 ℃,the maximum removal rate could reach 98. 6%. [Conclusion]MCTS has been successfully prepared and has a good adsorption behavior on Cr( Ⅵ).
