| 摘 要： | 采用浸渍－焙烧法制备了表面包裹氧化铝层的凹凸棒吸附剂并进行了除氟动态柱吸附效能实验。对含氟为４．２０ｍｇ／Ｌ的模拟水样经吸附滤柱后，其氟去除率可达９５％以上，累计氟吸附容量达到１０．５ｍｇ／ｇ凹凸棒，对吸附饱和改性凹凸棒再生后仍具有较高的吸附性能。

| Abstract: | An aluminum oside coated attapulgite absorbent was prepared by impregnating baking method and the removal effect of fluoride ion from water was studied by a dynamic absorption column.After the water containing 4.20 mg/L fluoride ion pass through the absorption column,above 95% of fluoride removal from the water was reached and accumulative absorption capacity was 10.5mg/g attapulgite.Higher absorption efficiency was remained after reliving the attapulgite absorbent of saturated absorption. |
