摘要
首先用均相沉淀法制备了Fe_(3)O_(4)@Y(OH)CO_(3)吸附剂,用SEM、TEM、IR、XRD和SQUID对其结构和性质进行表征;然后通过吸附磷酸盐溶液,考察了pH值、吸附时间对磷酸根吸附量的影响。实验结果表明,Fe_(3)O_(4)@Y(OH)CO_(3)为表面光滑的核壳结构,对磷酸根有较好的吸附性,pH值为3时,吸附效果最好;120 min时达到吸附平衡,平衡吸附量约为36.62 mg/g。
Firstly,Fe_(3)O_(4)@Y(OH)CO_(3) adsorbent was prepared by homogeneous precipitation method,and its structure and properties were characterized by SEM,TEM,IR,XRD and SQUID.Then,the effects of pH value and adsorption time on the adsorption capacity of phosphate were investigated by adsorbing phosphate solution.The results show that Fe_(3)O_(4)@Y(OH)CO_(3) is a core-shell structure with smooth surface and has good adsorption for phosphate.When pH value is 3,the adsorption is the best;the adsorption equilibrium was reached at 120 min and the equilibrium adsorption capacity was about 36.62 mg/g.
