摘要(Abstract)：

以某地富含铁的粉煤灰为原料,经两次磁选、湿磨后制得了实验所需的催化剂PFA,采用固体X-射线荧光光谱、粉末X射线衍射及扫描电镜法对样品进行了表征.以活性艳红X-3B为目标污染物,研究H2O2用量、反应溶液pH、催化剂用量及初始质量浓度等因素在常温下对其催化降解效果的影响.结果表明,最佳催化反应条件为:X-3B初始质量浓度150 mg.L-1,PFA用量1 g.L-1,H2O2用量1 mmol.L-1,pH=3.0,反应25 min,对X-3B的去除率可达到95%.PFA是高效的非均相类Fenton催化剂,对高浓度难生物降解的偶氮染料活性艳红X-3B具有优异的催化氧化活性.PFA循环10次实验表明,催化剂重复使用效果好.
