| 摘 要： | 以壳聚糖为基体,与环氧氯丙烷反应,然后与二乙烯三胺反应,制得二乙烯三胺接枝壳聚糖(CTSN)。经红外光谱FTIR分析和X-射线衍射分析表征了结构,在活化及接枝过程中未破坏壳聚糖中的吡喃苷六元环结构,其结构与预期结构吻合。初步研究了它对Pd2 、Ag 、Ni2 、Cu2 、Co2 、Cd2 金属离子的静态吸附性能,试验结果表明,CTSN对金属离子有较大的吸附容量,对Pd2 、Ag 离子的吸附容量分别为1.29mmol/g和1.15mmol/g。

| Abstract: | The novel diethylene triamine derivative was prepared by reaction between diethylene triamine and epoxy-activated chitosan. Its structure was confirmed by FTIR spectra analysis and X-ray diffraction analysis. The adsorption properties of this derivative for metal ions were also investigated. The experimental results showed that it has higher adsorption capacity for metal ions. The adsorption capacities for Ag and Pd2 were 1.29mmol/g and 1.15mmol/g, respectively. |
