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
A series of chitosan membranes and their N-acetylated counterparts were prepared and their differences in acidic solution stability and thermal and mechanical properties were studied. The differences were attributed to differences in crystallinity of the membrane as the result of preparation conditi
