摘要

•Chitosan-genipin films uptake iron ions in aqueous acidic solutions.•The uptake occurs in the presence of α-hydroxypolycarboxylic acids.•Ternary complexes of iron ions, carboxylic acids, and Ch-Ge films are formed at pH < 3.5.•Electrostatic interactions explain the iron ions sorption by Ch-Ge films.
