PHYSICO-CHEMICAL PROPERTIES OF INTERPOLYELECTROLYTE COMPLEXES BASED ON LOW-MOLECULAR CHITOSAN
Abstract
The features of the formation of interpolymer complexes based on low molecular weight chitosan and a nonionic water-soluble polymer in aqueous solutions are discussed. Complexing properties were studied by spectrophotometric method using aqueous solutions of salts of low-molecular electrolytes CuSO4 and CoCl2 for Cu2+ and Co2+ cations. The study of the dependence of optical density on the concentration of the reagent was carried out under the selected optimal conditions λmax, pH = const, increasing the concentration of the reagent for complete binding of metal ions into the complex under study. To determine the composition of the complex, the minimum amount of reagent required for complete binding of the metal ion to be determined into the complex was established. The data of IR spectroscopy of the obtained complexes are presented.
