Abstarct: The present study aimed to use powdered zeolite (PZ), granular zeolite (GZ) and modified granular zeolite with Manganese nano oxide (MGZ) adsorbents to achieve a high removal rate of aluminum from aqueous solution in a batch system. In this research, granular zeolite with temperature modification of powdered zeolite was first made and then, by means of thermal degradation, GZ was modified by manganese oxide nanoparticles. The prepared three adsorbents were used to remove aluminum from aqueous solution in different conditions. Properties of the adsorbents were determined by SEM, EDX, XRD and FTIR analyzes. The effect of important factors on the adsorption process, including adsorption dose, pH of solution, contact time and initial concentration of the pollutant were investigated. baxsed on the results, it was determined that the maximum aluminum removal percentage from aqueous solution at three initial concentrations 1, 5 and 10 mg/L of aluminum by ZP were obtained at 120 minute 90.5, 88.2 and 83.1% respectively, for GZ at 60 min, 100, 99.4 and 98.9% respectively and for MGZ at 15 minute 99.2, 99 and 98.6% respectively. The results of FTIR analysis indicated that 4-peaks corresponding to C-H and C=C groups eliminated after modification of granular zeolite by manganese oxide nanoparticles. This result could be the reason of better adsorption behavior of this adsorbent against other adsorbents use in this study. According to the results, the adsorption process of aluminum by PZ, GZ and MGZ follows the Freundlich isotherm and second-order kinetic adsorption model. ZG and ZGM exhibit higher efficiency and facile separation from aqueous solution in compare with ZP. Also aluminum removal procedure using ZGM occurred in lower contact time and less amount of adsorbent in compare with two other absorbents.
