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 %。
The hydrotalcite was prepared by nucleation / isolation method, and the phase of the sample was characterized by X-ray diffraction. The hydrotalcite could reabsorb water and anion under certain conditions after roasting, which partially restored the structural memory effect of layered structure. Hydrotalcite calcined at different temperatures to remove chloride ions. The experimental results show that the hydrotalcite calcined at 400 ℃ has the highest chloride removal rate of 39.0%.
