摘　　要：将具有光催化潜力的Zn、Ti金属元素引入凹凸棒粘土(ATPs)结构中,采用浸渍法制备了一系列Zn/TiATPs,并用作光催化剂进行盐酸四环素光降解实验。考察了金属离子配比、焙烧温度等对光催化性能的影响。结果表明,Zn/Ti金属摩尔比为3∶1,煅烧400℃时制备的Zn/Ti-ATPs具有良好的光催化性能。在可见光照射120 min条件下,20 mg Zn/Ti-ATPs对20 mg/L盐酸四环素的光催化降解率可达91.29%。In order to make the attapulgite clay（ ATPs） have the photocatalytic performance,and put the photocatalytic potential metal elements Ti and Zn into the ATPs structure. Then prepared a series of Zn /Ti-ATPs by impregnation method and photocatalytic degradation of the tetracycline hydrochloride. The influence of the ratio of metal ions,roasting temperature,etc. on the properties of photocatalytic materials was investigated. The results show that with the Zn /Ti molar ratio of 3∶ 1,and the roasting temperature of400 ℃,the Zn /Ti-ATPs has a good photocatalytic performance. The photocatalytic degradation of tetracycline hydrochloride can be made as high as up to 91. 29% in 120 min under the irradiation of xenon lamp light.
