以过氧化氢作为解聚剂,氧化制备壳寡糖。研究了壳寡糖对锌离子的吸附动力学行为,得到了较为理想的合成产物。用紫外光谱、红外光谱、元素分析对配合物的组成进行了表征。结果表明,该壳寡糖平均聚合度为6,壳寡糖与锌离子之间发生了配位作用,其吸附行为可用Langmuir单分子层吸附机理解释,并推算出配合物中壳寡糖与锌的配位比为3:1,壳寡糖与锌配合物可能的组成为[Zn(COS)3]SO4·6H2O。
Hydrogen peroxide as a depolymerization agent, oxidation of chitooligosaccharides. The adsorption kinetics of zinc ions by chitooligosaccharides was studied and the ideal synthesis products were obtained. The composition of the complex was characterized by UV, FTIR and elemental analysis. The results showed that the chitooligosaccharides average polymerization degree of 6, chitooligosaccharides and zinc ion coordination occurred between the adsorption behavior can be Langmuir monolayer adsorption mechanism to explain and calculate the complex chitooligosaccharides and zinc The coordination ratio of chitosan oligosaccharide with zinc is 3: 1, and the possible composition of chitooligosaccharides and zinc is [Zn (COS) 3] SO4 · 6H2O.
