Abstract:
Under certain conditions, layered double hydroxides(LDH) after beingcalcined can be used for absorbing water and anions, in order to resume the structural memory effect of the layer-shaped structure.The application of calcined Mg-Al-CO3 LDH tothe treatment ofchloride-containingwastewater is studied.Experiments showthat when the ratioofMgand Al is 4∶ 1, calciningtemperature 500 ℃,LDH dosage 2.0 g/L,and treatment temperature 30 ℃,the treatment efficiencyis the best.

摘要：
利用水滑石(LDH)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，研究了焙烧镁铝碳酸根水滑石(CLDH)在处理含氯废水中的应用。实验表明，当CLDH镁铝比为4∶1、焙烧温度为500℃、水滑石质量浓度为2.0g/L、处理温度为30℃时，CLDH对氯离子的处理效果最佳。
