| 摘 要： | 介绍了一种将钠基累托石改性制成聚羟基铝铁改性累托石的方法,用XRD分析了其间层结构,并将该吸附剂应用于舍氟饮用水处理.研究了不同类型累托石的吸附性能,考查了反应时间、pH值、吸附剂用量和溶液初始浓度对吸附反应的影响,并对反应时间、pH值以及吸附荆用量做了三水平三因素正交实验,对吸附反应进行了Freundlich吸附等温线拟合,探讨了吸附反应的机理.结果表明,该方法制备的聚羟基铝铁改性累托石可以将含氟5mg/L的饮用水的处理到0.1mg/L,去除率达98%.

| Abstract: | The paper introduced a kind of preparation of polyhydroxy-aluminium-iron with Na rectorite,and we analysed its interbedded structure with the XRD,and apply the sorbent to the disposal of drinking water contaminated with fluoride.The adsorption property of modified rectorites were researched,and the effects of reaction time,pH,the dosage of the sorbent and the original concentration were studied,and we also designed orthogonal experimental to discuss the effects further.The adsorption isotherm was fitted wel... |
