摘要:
以纤维素为原料，采用高碘酸钠氧化后接枝支化聚乙烯亚胺，制备超分子结构纤维素基吸附剂（Supramolecular aminofunctionalized cellulose，SAC），并分析SAC去除Co 2+离子的能力，并通过FTIR、EDS、吸附动力学和吸附等温线模型探究其去除机理。结果表明：SAC能快速去除Co 2+离子，在10 min内达到吸附平衡；吸附容量随着pH值的增加而增加，吸附效率随着温度的增加而降低；SAC对Co 2+离子的吸附是一个自发的放热过程，符合伪二级吸附动力学和Langmuir等温吸附模型，SAC对Co 2+最大吸附容量为52-63 mg/g；SAC对Co 2+离子的高效去除效率是静电作用、配位络合及离子交换共同作用。为水体中Co 2+离子的去除提供了一种新方法。
