The preparation and characterization of chitosan was set up as a research-oriented comprehensive experiment in the course of Primary Training of Chemical Research in the summer semester of USTC. With the local lobster shell as the raw material, we inquired into the preparation of chitosan after a series of reactions such as deproteinization, desalination, decoloration and deacetylation. The physicochemical properties of chitosan were characterized by FT-IR, 1H-NMR, viscosity measurement and titrametry.

Key words: Lobster shell, Chitosan, Preparation and characterization, Research-oriented, Comprehensive chemical experiment
