  • An novel nano titania loaded bentonite organic absorbent based on butyl titanate and organic bentonite was prepared by sol-gel method. The properties of absorbent were characterized by various experimental techniques, such as X-ray diffraction (XRD), BET, scanning electron microscope (SEM). The results showed that nano titania was laoded on the organic bentonite, the basal spacing and specific surface area of absorbent were increased significantly. The influences of preparation and adsorption conditions on the adsorption performance were also studied. The results indicated the optimum reaction condition was as follows:pH 6, the calcination temperature 300℃, the calcination time 4 hours, and the nanometer titania content 80%.Under the conditions of pH of 6,adsorption time of 5 h, initial concentration of oxytetracycline hydrochloride of 25 mg·L-1,the adsorption capacity could reach 97.3%.
