Electrolytic manganese residue（EMR） is a large amount of solid waste deposited in the open air,during the stockpiling process,toxic pollutant Mn2+ will be released. In order to effectively utilize EMR and eliminate the environmental hazards of Mn2+,zeolite was prepared by microwave heating and alkali fusion method using electrolytic manganese residue as raw material,and it was used to adsorb Mn2+.Then,the factors of initial Mn2+ concentration,solution pH,adsorption temperature and adsorption time on the adsorption effects of Mn2+ were discussed.The results showed that synthetic zeolite had a better performance for Mn2+ removal and the maximum adsorption quantity for Mn2+ was 79.18 mg/g under the conditons such as initial Mn2+ concentration of 500 mg/L,solution pH of 6,adsorption time of 2 h and adsorption temperature of 50 ℃.The adsorption behavior of zeolite from electrolytic manganese residue on manganese ions was investigated.Results showed,the adsorption of Mn2+ on the surface of zeolite fitted well to the pseudo second-order equation,the Langmuir equation model was found to be more suitable to explicate the experimental equilibrium isotherm results than Freundlich equation model.This study revealed that EMR-based zeolite had a good recycling performance and potential application prospect in heavy metal wastewater treatment.
