摘　　要：文中利用我国东北地区优质的硅藻土,对硅藻土原土经碱浸水洗处理后,与FeCoMg复合氧化物高温煅烧形成FeCoMg复合氧化物-硅藻土复合材料,在Fenton反应体系下,研究对亚甲基蓝的吸附、降解效能.本文研究了反应时间、H_(2)O_(2)浓度、复合硅藻土投加量等因素对亚甲基蓝降解效能的影响.研究表明复合硅藻土对亚甲基蓝吸附降解的最佳工艺条件为:pH值呈中性,复合材料的加入量为4 g/L,H_(2)O_(2)的加入量为0.2 mL,在反应4小时后亚甲基蓝的去除率可达98.3%.In the present work,the diatomite with high quality in northeast of our country afterrinsing and sifting,with FeCoMg composite oxide formed FeCoMg composite oxide-diatomite composite materials at high temperature calcinations.Under the Fenton reaction system,the influence factors such as reaction time,H_(2)O_(2) concentration,amount of composite diatomite for removal efficiency of methylene blue were investigated.The optimized technological conditions for adsorption and degradation of 50 mg/Lwith removal rate of 98.3%are 4 g/L composite diatomite,0.2 mL(30%)H_(2)O_(2),and 4h of reaction time.
