| 摘 要： | 采用共沉淀法制备碳酸型及硝酸型Mg-Al-LDH(层状双氢氧化物)粉体,并对两种不同阴离子的LDH样品进行X射线衍射(XRD)及红外光谱表征;又将其作为吸附剂,对水中磷酸根离子的去除性能进行了系统研究。实验结果表明,两种LDH的晶体结构基本相似;其对废水中磷酸根离子具有很好的去除效果,且碳酸型LDH除磷效果更佳。通过对模拟废水及实际废水进行吸附实验,得到了LDH除磷的最佳条件。镁铝LDH在废水除磷方面具有较好的应用前景。

| Abstract: | Carbonated and nitric Mg-Al-LDH were synthesized by the coprecipitation method,and the products were characterized by XRD and IR.Taking them as adsorbent,the removal capacity of phosphorus ions in water was studied.Experimental results showed that their crystal structure are resemble;the phosphate ions from wastewater has a good removal,and removal carbonated LDH better.The best conditions for removal LDH was obtained by simulated wastewater in adsorption experiments and real wastewater.Mg-Al LDH in the pho... |
