Аннотация:Chitosan is a promising material for the manufacture of edible films and medicine, but this
biopolymer has a low solubility and brittleness, so there is a need of chemical modification of
chitosan for the creation on its basis of the composites with novel properties [1].
In this work, we studied the initial samples of chitosan and composites based on it with
iron (II) hydroxide and sulfate, as well as samples of the same materials subjected to various typ
