Performance of strong acid cation resin D072 for the adsorption of Fe (II) from aqueous phase
Resin D072 was more useful on the adsorption of Fe2+ as a heterogeneous catalyst in the presence of H2O2,which had high catalytic activity in the decolorization of reactive red KE-3B.The conditions of the adsorption of Fe2+ by D072 were optimized,including the initial pH,the Fe2+ concentration and reaction time.It was found that the optimal pH was pH3.The optimal initial concentration of Fe2+ and reaction time were 840 mg L-1 and 60 min,respectively.It illustrated that the adsorption behavior of Fe2+ by D072 obeyed Freundlich adsorption model.The decolorization reaction of reactive red KE-3B was still faster though the catalyst already used 10 times because Fe leaching from the catalyst was negligible.The heterogeneous catalyst seems to be viable method for achieving significant decolorization of dying industry wastewater.
