摘要
采用晶核 /隔离法制备水滑石 ,并用X射线衍射技术对样品物相表征 ;利用水滑石焙烧后在一定条件下可重新吸收水和阴离子 ,从而部分恢复层状结构的结构记忆效应 ,考察了不同温度焙烧的水滑石去除氯离子的性能。实验结果表明 ,4 0 0℃下焙烧的水滑石对氯离子的去除率最高 ,达到 39.0 %。
Hydrotalcite were prepared by nucleation and crystallization parting method and characterized by X-ray diffraction technology. Because calcination hydrotalcite can absorb water and anion in some condition to partly resume laminate structure , which is called structure anamnesis effect,removal performance of chlorine anion by hydrotalcite calcined at different temperatures was investigated The experiment results show that the removal ratio reaches the highest at 400 ℃,which is 39%.
