| Abstract: | 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. |
| |
| Keywords: | chitosan deacetylating degree titration error indicator |
