摘要: 本文探讨了壳聚糖对Ca(Ⅱ)的吸附条件,并对其吸附行为进行了详细研究,发现Ca(Ⅱ)与壳聚糖在发生配位反应形成壳聚糖-钙(Ⅱ)配位聚合物的同时,也产生了吸附作用。动用元素分析法、红外光谱法和紫外吸收法对原料及配合物的结构及光学性能进行了表征。

Abstract: The adsorption conditions and adsorption behavior of Ca 2+ on chitosan were investigated.The c oordi-nationpolymerofCa 2+ withchitosanwas synthesized.Elem entanalysis andIRandUV -VISspectr aassayresults showed that the chitosan formed a coo rdination polymer with Ca 2+ and adsorbed particle Ca 2+ too.Hence,there would be a prospect of developing pro bably a health food or phamaceaitcal ingredient.
