Abstract
Chitosan is a biopolymer obtained from chitin, one of the most abundant biopolymers in nature. Numerous applications of chitosan are well known in the biomedical, environmental, and industrial fields, and the potential applications are considerable. This work reports a new spectrophotometric method to determine chitosan concentration accurately. The method is based on the deamination of chitosan by nitrite in acidic conditions, followed by a carbohydrate determination by the anthrone reagent.
