摘　　要：采用四氯化钛水解法制备了纳米TiO_2催化剂,利用XRD和TEM对其结构进行了表征分析,并研究了其对盐酸黄连素的光催化去除效果。结果表明:纳米TiO_2催化剂为锐钛矿和金红石的混合晶型,平均粒径约25nm,并且具有良好的光催化活性;当盐酸黄连素溶液浓度为10 mg/L,催化剂用量为1.6 g/L,在300 W汞灯照射条件下反应5h时,其对盐酸黄连素的光催化去除率达80%以上。The nano TiO2 catalyst was prepared by the hydrolysis of four titanium chloride. The structure was characterized by XRD and TEM, and the photocatalytic degradation of berberine hydrochloride was studied. The results show that the nano TiO2 catalyst is a mixed crystal of anatase and futile, with the average particle size of about 25 nm, and has a good photocatalytic activity for berberine hydrochloride. When the concentration of berberine hydrochloride solution was 10 mg/L and the dosage of catalyst was about 1.6 g/L, the removal rate of berberine hydrochloride was more than 80% under the condition of 5h irradiation with 300 W mercury lamp.
