Zeolite was modified by HNO3 solution and NaOH solution in order to improve the adsorption performance. The characterization of the modified zeolite by scanning electron microscope(SEM) and infrared spectroscopy(IR) was displayed. In order to obtain the optimum conditions for adsorption of Sb3+ and Mn2+, resulting in a better removal efficiency, parameters such as the concentration of HNO3 and NaOH, dosage of modified zeolite, adsorption time, initial concentration and adsorption temperature were examined. Results showed that the zeolite modified by 0.8 mol/L HNO3 had better adsorption rate for Sb3+, the zeolite modified by 1.4 mol/L NaOH had better adsorption rate for Mn2+, and the highest adsorption rate of Sb3+ and Mn2+ were 89.1% and 99.6%, respectively. Isotherm process was well predicted by Freundlich model when adsorption Sb3+ by using HNO3 modified zeolite, and the Langmuir model fitting the equation well when adsorption Mn2+ by using NaOH modified zeolite. Kinetic process was predicted well by pseudo second-order model when adsorption Sb3+ by using HNO3 modified zeolite and adsorption Mn2+ by using NaOH modified zeolite .
