凹凸棒石/纳米铁复合材料的制备工艺及对亚甲基蓝废水的处理
Preparation Process of Attapulgite/Nano Iron Composite and its Removal Application to Methylene Blue
摘要
Abstract
This is an article in the field of ceramics and composites.Methylene blue is a typical pollutant industrial wastewater.It will bring great harm to the water body if it is discharged arbitrarily without treatment.We prepared a kind of attapulgite/nano iron composite(DDBAC/ATP/nZVI),that the attapulgite was roasted,organic modified and then loaded with nano iron(nZVI)by liquid-phase reduction.The optimum preparation process is obtained:attapulgite raw soil is calcined at 300 ℃ for 1.5 h,20 mmol/100 g benzalkonium chloride(DDBAC)is added,then ultrasonic is used for 20 min,and then nano iron is loaded by liquid-phase reduction method.The ratio of iron to soil is 1:3,KBH4 concentration is 0.25 mol/L and reaction time is 3 h.The XRD,FTRI,SEM,XPS,BET confirm that DDBAC and nano iron are successfully loaded on the surface of attapulgite.The maximum removal of methylene blue by DDBAC/ATP/nZVI is 114.94 mg/g,and the application performance of the DDBAC/ATP/nZVI remains stable within 60 days.关键词
