Abstract

Abstract

With electrolytic manganese slag as raw material, after the weak acid complexing, activation of alkali-melt, aging at room temperature and crystallization of hydrothermal synthesis system, analcite ANA-A and ANA-S was prepared by adding aluminum and silicon respectively. Performance of the two kinds of analcime such as chemical composition, crystal phase structure, microstructure, and specific surface area were analyzed by using characterization methods of XRF, XRD, SEM, EDS and BET. The results showed that the analcite could be successfully synthesized with both the addition of aluminum and silicon at the calcination temperature of 750 ℃, the synthesis temperature of 180 ℃, and the hydrothermal reaction time of 8 h. Further study on two kinds of zeolite Pb²⁺ in aqueous solution of static adsorption showed that ANA-A and ANA-S could fitting Langmuir isotherm model well, accorded to the monolayer adsorption. Their saturated adsorption capacity were 161.29 mg/g and 185.19 mg/g, and the initial concentration of 100 mg/L of Pb²⁺ removal rate reached 93.69% and 95.47% respectively, comlied with the lagergren quasi-second order kinetics model, and were defined as chemical adsorption. ANA-S has better adsorption effect between the two adsorbers.
