The adsorption behavior of Fe2 + by chitosan was studied and the conditions were optimized. The ideal synthesis products were obtained. The structure of the complex was characterized by FTIR and UV spectroscopy. The composition of the complex was determined by chemical analysis and elemental analysis. The non-isothermal kinetic data were linearly simulated by TG DSC and the commonly used 22 mechanism functions The most thermodynamic thermodynamic parameters and kinetic parameters (E and A) were obtained during the decomposition of the complex.
