摘要
研究了沸石经过高温烘烧、盐处理、酸处理和先碱后盐活化处理后的除氟效果,并在分析沸石结构特征和活化实验结果的基础上,探讨了沸石除氟的机理。试验结果表明:先用2%的NaOH溶液浸泡24h,反复冲洗至pH值为中性后,再用2%的硫酸铝钾溶液浸泡36h,活化效果最佳。
The Fluorin removal effect was studied after it had been activated by different methods as burn, dealing with salt, acid or salt after alkali. The experimentation result indicat：The zeolite particles soaked in 2% NaOH solution for about 24h, washed it to neutral, and then soaked in 2% KAI（SO4）2 solution for about 36h is better method, also the mechanism was discussed.
