丙酮酸壳聚糖衍生物的制备及其吸附性能研究
Synthesis and Adsorption Properties
of Chitosan Modified by Pyruvic Acid
摘要
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.
