Abstract The chitosan microspheres were prepared by inverse phase suspension method in this study. The chitosan was modified by reducing Schiff`s bases formed from the reaction of n-heptaldehyd and chitosan. The structure of microspheres were characterized by FTIR and SEM. The effects of adsorption conditions, such as time, pH, temperature ,the concentration of 2,4-dinitrophenol and the amount of sodium chlorind on the adsorption were investigated. The experimental result indicated that micropheres were able to adsorb 2,4-dinitrophenol very well. In an aqueous solution at pH 3.6，the adsorption reached to 400 mg•g-1 in 1 hour. The adsorption data of 2,4-dinitrophenol on the modified chitosan microspheres was fitted to the Freundlich isotherm.
