Synthesis and Research of Chitosan Tartrate Complexes

Under certain conditions, chitosan reacts with tartaric acid to form chitosan tartrate complex.Experiment resultsshowed the content of tartaric acid in the complex can be correctly determined by potentiometer titration.The more tartaric acidis used during the process,the more the content of tartaric acid in the complex is.The viscosities of complexs are more than thatof chitosan itself,and as the content of tartaric acid increases,the viscose of complex increases.
