| 中文摘要: |
| 壳聚糖脱乙酰度采用碱量法，按强碱－强酸型测定，不管选用何种指示剂，均可产生不容忽视的滴定误差。 |
| English Summary: |
| In
this study the experiments showed that the alkalimetric estimation of the deacetylation
degree of chitosan by the strong base-strong acid reaotion could cause the titration error
not to be ignored,no matter what indicators would be sued. |
