| Abstract: | In this paper a new method for determining the degree of deacetylation of chitosans is given. The C and Sb electrodes are put in the titration solution and connected directly to an oscillograph. During the acid-base tiration a sudden change of the fluorescent spot position can be used to indicate the end point of titration of chitosans. The end point is visible and sensitive. The method has been shown to be reliable and simple. |
