Abstract
Macroporous amidoxime chelating resin was prepared in order to remove Fe3+ from citric acid. The key influence factors, kinetics, thermodynamics, mechanism of adsorption were analyzed with macroporous amidoxime chelating resin which was prepared by chemical modification of acrylonitrile polymer. Results indicated that adsorption amount of Fe3+ significantly decreased with the increase of citric acid concentration and the saturated adsorption time prolonged with the increase of concentration of citric acid. The adsorption equilibration of macroporous amidoxime chelating resin achieved after 2.5 h in solution without citric acid and the adsorption amount could reach to 14.01 mg/g. Moreover, the absorption isotherm followed the Freundlich model well. DH and DS were more than zero in the range of 303-323 K, whereas DG was less than zero and the adsorption of Fe3+ by macroporous amidoxime chelating resin was a spontaneous and decalescence adsorption process. This research will be helpful for providing new methods to deal with organic acid solution containing Fe3+.
