摘要
天然红辉沸石经过氯化铝及氯化镁共同改性后,制备出改性红辉沸石。研究了改性红辉沸石和天然红辉沸石对生活污水中CODcr的吸附效果,表明改性红辉沸石的吸附效果明显优于红辉沸石,并通过X射线粉末衍射、热重分析、红外光谱对改性红辉沸石表面结构进行了表征。
Modified stellerite is prepared from natural stellerite through the common modification of aluminium chloride and magnesium chloride.This paper researches the effects of modified stellerite and natural stellerite on absorbing CODcr in domestic sewage,and the results indicate that modified stellerite has obviously superior absorbing effect to natural stellerite.It also characterizes the surface structure of modified stellerite through X-ray powder diffraction,thermogravimetric analysis and infrared spectrum.
