摘　　要：采用碱性沉积蒸发法对石英砂进行改性,XRD和SEM的结果表明Fe 2O 3成功负载到石英砂表面。利用该材料改性石英砂催化过硫酸钾降解亚甲基蓝,系统考察了pH,过硫酸钾投加量,材料投加量,温度等影响因素对降解效果的影响。本文提供了一种经济、高效的类Fenton反应催化剂的制备方法。In this work,the quartz sand was modified via the alkaline deposition evaporation method and used to catalyze potassium persulfate for the removal of methylene blue.XRD and SEM showed that Fe 2O 3 was loaded on the surface of quartz sand successfully.Furthermore,the effect of initial pH,persulfate dosage,catalyst amount,and temperature was investigated systematically.It provides an economical and efficient preparation method of Fenton-like catalyst.
