Effect of Chemical Treatment on the Degree of Deacetylation of ChitosanChitosan wide range of application is highly dependent mainly on the presence of the reactive amino groups and its degree of deacetylation (DDA) is one of the main parameters characterizing chitosan. Chitosan was produced from ...
Object To study the degree of deacetylation of chitosan and its residual amount left over in the clarified products when chitosan was used as a clarificant. Methods The free amino group in the deacetylated chitosan was determined by linear titration. Results The degree of deacetylation of chitosan...
Colloid titration was used to determine the substitution degree of deacetylation(DD) of chitosan.The effect of solution pH value,concentration and sodium chloride concentration on colloid titration were discussed.The advantages and disadvantages of colloid titration were compared with electrolytic titration ...
The FTIR spectrophotometric determination of the degree of deacetylation (DD) of krill- and shrimp-derived chitosans was optimized with respect to sample type (film or KBr pellet), evaluation procedure (peak height vs. area), measurement and reference absorption bands, etc. (Table 2, Fig. 5)...

The MW of chitosan is analyzed using GPC. The degree of deacetylation (DD) is measured by FTIR. OECD Guideline for Testing of Chemicals No 423 is used for evaluation of acute oral toxicity tests of nonirradiated and irradiated chitosan using mice with body weight (BW) ranging from 20 to ...
Determination of the degree of deacetylation of chitin and chitosan by X-ray powder diffraction A new method to determine the degree of deacetylation (DD) of α-chitin and chitosan in the range of 17–94% DD using X-ray powder diffraction (XRD) is pro... GX Zhang - 《Carbohydrate ...
