Abstract In order to efficiently remove dyes in waste water, aluminum-pillared montmorillonite (Al-mt) was prepared by wet modification of montmorillonite using sodium-based montmorillonite as raw material. XRF, FTIR, XRD were used to characterize it; the refractory azo dye Orange IV was used to prepare simulated wastewater, and the adsorption performance and adsorption isothermal kinetics of Al-mt for Orange IV were studied. The results showed that at 25 ℃ and pH value of 5, 50 mg/L orange IV was adsorbed for 30 min to reach the adsorption equilibrium, the adsorption rate was 95.90%, and the adsorption process satisfies the Freundlich isotherm adsorption model and the pseudo-second-order kinetic equation.
