磁性壳聚糖微球的制备及对Cr(Ⅵ)的吸附研究
Study on the Preparation of Magnetic Chitosan Microspheres and Its Adsorption on Cr(Ⅵ)
摘要
Abstract
[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 tem-perature 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 suc-cessfully prepared and has a good adsorption behavior on Cr(Ⅵ).关键词
