Modified tobermorillonite (AHTOB) with a specific surface area of 570 m2/g was prepared by heating and acidification of tobermorillonite (TOB). The structure and specific surface area and pore size of the modified tobermorillonite were characterized by X-ray diffraction and N2 adsorption-desorption. The adsorption properties of three adsorbents on methylene blue solution (MB) were investigated by static adsorption experiments, and the adsorption mechanism of modified TOB on MB was analyzed. The effects of adsorbents, solution pH value, initial MB concentration, adsorption time, and temperature on the adsorption behavior were investigated, and the thermodynamic and kinetic behaviors of AHTOB adsorbed on MB solution were investigated. The adsorption of MB was analyzed in 50 mL of MB at a concentration of 10 mg/L. The results show that the adsorption rates of unmodified TOB, HTOB, and AHTOB on MB are 50.00%, 53.72%, and 97.35%, respectively. At different initial concentrations of MB, the maximum adsorption capacities of TOB and HTOB are 102.36 mg/g and 113.80 mg/g, and the adsorption capacity of AHTOB on MB is 248.01 mg/g. The adsorption efficiency of AHTOB modified by heating and acidification compound is improved. The optimal conditions for adsorption are pH value of 5-7, shaking time of 30 min, and temperature of 20-25℃.
