| 摘 要： | 利用壳聚糖C2位上活泼氨基与丙酮酸进行大分子反应，采用正交试验法优化合成条件，合成了带有高取代羧基、能溶于水的功能聚合物－丙酮酸改性壳聚糖（简称PCTS），研究了PCTS对Cu^2 ,Zn^2 ,Co2 等重金属离子的吸附性能，其对低浓度金属离子去除率分别达到100％，99．8％和40．5％，与壳聚糖、水杨醋改性壳聚糖相比，溶解性能和吸附性能有较大提高。

| Abstract: | Chitosan functional polymer containing schiff-base group was synthesized by chemical modifi
cation of amino group of chitosan with pyruvic acid. The synthesis conditions were optimized by orthogonal
test method. The adsorption properties of PCTS for Cu(Ⅱ), Zn(Ⅱ), Co(Ⅱ) were also investigated. The
results show that the percentage of removing low concentration metal ions are 100%, 99.8% ,40.5%, re
spectively. In comparison with chitosan and chitosan modified by salicylaldehyde, the solvencies and ad
sorption properties are improved. |
