The adsorption isotherm and adsorption reaction kinetics of carboxymethyl chitosan (CMCS) for Fe²⁺ have been studied.The results showed that CMCS appeared a good adsorbent for Fe²⁺ in solution with pH 6~8 and the adsorption capacity of CMCS increased with the increase in its carboxyl groups.The adsorption isotherm of CMCS for Fe²⁺ at 20℃ was fitted good for the Langmuir equation.
