摘　　要：以钛酸四丁酯为前驱物,采用溶胶-凝胶法,在低温或常温下通过溶液中发生水解、聚合等化学反应,先生成溶胶,进而生成具有一定空间结构的凝胶,然后经过干燥、减压、热处理,制备出纳米TiO2并在砂粒载体上附着,并详细研究了砂粒负载TiO2对洗涤污水的光催化降解等。The text with tetrabutyltitanate as precursor,adopted sol-gel method,passing to take place hydrolysis and polymerization etc.chemical reaction in the solution under the low temperature or the normal temperature.First became dissolve gum,then born the gel which had certain space structure.Pass by dry,decompression and hot processing,making the nano-TiO2 carried in the sands beads also up adhere to,and studied on the light-catalyst degraded a solution of sands s beads loaded TiO2 to washing-up sewage.
