## Abstract Functional properties of the amino polysaccharides, chitin and chitosan, vary significantly with their acetyl content. The acid hydrolysis‐HPLC method offers good accuracy and precision to assay the acetyl content regardless of the solubility of the sample. In this research, the hydroly

A simple and rapid method for the quantitative determination of N-acetyl groups in chitin-chitosan samples consists of an acid hydrolysis conducted at high temperature with a mixture of sulfuric and oxalic acids. The acetic acid formed is determined by spectrophotometry at 210 nm after separation fr
The adsorption of humic acid onto chitin and chitosan has been investigated. The uptake of humic acid from aqueous solution was determined from changes in concentration, as measured by ultraviolet-visible spectroscopy. The decrease in humic acid removal was observed with the increase in pH. A signif
## Abstract Commercial chitosans were subjected to controlled acid hydrolysis and their degrees of deacetylation (DD), molecular size and rheological flow profiles determined (pre‐ and post‐hydrolysis) by ^1^H‐NMR spectroscopy, high‐performance size‐exclusion chromatography and rheometry, respectiv
