摘要: 以钛酸丁酯和有机膨润土为原料，采用溶胶凝胶法制备了有机膨润土负载纳米TiO2吸附剂。通过XRD、BET、SEM等方法对吸附剂进行表征。结果表明，纳米TiO2已负载在有机膨润土上，有机膨润土负载纳米TiO2材料的层间距发生了明显变化，且其比表面积增加。同时对影响吸附盐酸土霉素的因素进行了考察，吸附剂最佳制备条件为煅烧温度300℃，煅烧时间4 h，TiO2含量80%，在pH=6，盐酸土霉素溶液浓度为25 mg·L-1，吸附时间为5 h时，对盐酸土霉素的吸附率可达97.3%。

Abstract: 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%.
