| 摘 要： | 为了提高天然沸石的除氟能力，采用了高温焙烧、酸碱处理和硫酸镁浸泡等方法活化天然沸石，研究其除氟性能.结果表明，各种方法均可在一定程度上提高沸石的吸附能力，其中以经过高温焙烧、硫酸浸泡、硫酸镁改性途径活化得到的沸石除氟效果最佳，改性后的沸石除氟容量是未改性的3.97倍，初步显示出该沸石良好的应用前景.

| Abstract: | To improve the fluoride-absorption capacity of natural zeolite, a study on activation method, including roasted at high temperature in a muffle furnace, soaked in inorganic acid or inorganic basic solution, modified by magnesium sulfate, and defluorination performance of natural zeolite have been carried out. The resuhs showed that fluoride-absorption capacity of natural zeolite treated with all those methods mentioned in the paper can be increased to some extent, especially, the zeolite activated through the way of being roasted in muffle furnace, soaked in H2 SO4 solution and modified in magnesium sulfate solution, can effectively remove fluoride from water. The absorption capacity of activated zeolite is 3.97 times of that of unactivated one,which shows a good prospect in practice. |
