摘 要: 以TiCl4、氨水等普通无机盐为原料,采用直接水解常压液相反应合成具有金红石相和锐钛矿相的混晶纳米TiO2粉体.研究了前驱体在不同温度下焙烧所得样品的光催化性能,并用此产品在太阳光照射下对3种工业含氰废水进行降解处理,结果表明,混晶纳米TiO2可有效降解废水中的大部分有毒氰根(CN-),使其含量远低于国家排放标准. Mix-crystal nanometric TiO2 compound was prepared by normal pressure liquid-phase reaction, using TiCl4 and ammonia as the raw materials. The experiment studied the photocatalysis of the sampie at different calcination temperature. Three industrial wastewater of CN^- was degradated with the sample under sunlight. The result indicated that CN^- was majority degradated, the content of which below national emission standard.
