Abstract:

以氧化镁为致孔剂,利用环氧氯丙烷交联β-环糊精,合成多孔β-环糊精交联聚合物(β-CDP).考察β-CDP对亚甲蓝(MB)的吸附动力学、热力学讨论吸附的作用机理,并考察pH值、MB的初始质量浓度、吸附剂的投入量、吸附时间及吸附温度对β-CDP吸附MB的影响.结果表明:在室温下,水体的pH值为6.54,MB初始质量浓度为40 mg?L-1,吸附剂投入量为0.6 g?L-1,β-CDP的最大吸附量为62.6 mg?L-1;吸附符合准二级吸附动力学模型和Freundlich等温吸附模型;结合颗粒内扩散模型,以及吸附热力学数据ΔH为20.50 kJ?mol-1,ΔG为-6.1~-7.5 kJ?mol-1,可得该吸附为异质表面的多因素联合控制物理吸附.
