Results The degree of deacetylation of chitosan was found to be about 80%.
结果壳聚糖澄清剂的脱乙酰度约80 %，在澄清液中壳聚糖残留量小于0。
The degree of deacetylation of chitosan was determined directly by 1st derivative UV spectrophotometry using hydrochloric acid as solvent and N acetyl D glucosamine (ACGLSM) as standard.
以盐酸为溶剂，N 乙酰基D 葡萄糖胺为标准品，用紫外一阶导数光度法直接测定壳聚糖的脱乙酰度。
The degree of deacetylation of chitosan prepared by the optimum condition is 88.53%, the viscosity average molecular mass is 9048. The experimental result mainly accorded the prospective desire.
