摘要
在这项工作中,制备了一种以金属有机配位聚合物(MOFs)材料(HKUST-1)为载体,通过KCoFC(Co(NO_3)_2与K_4Fe(CN)_6反应产物)功能化修饰后的新型复合材料,并通过FTIR、SEM、XRD对其进行表征。研究初始Cs^+浓度、吸附时间、溶液pH值对吸附效果的影响,用吸附动力学和吸附等温线模型研究HKUST-1/KCoFC对Cs^+的吸附过程。实验表明:在40min内,Cs^+吸附量迅速增加,复合材料对Cs^+吸附量最佳的pH为8;HKUST-1/KCoFC对Cs^+吸附过程符合准二级动力学和Langmuir模型。
In this work,a novel composite material was prepared by using metal-organic frameworks(MOFs)material(HKUST-1)as a carrier and functionally modified by KCoFC(Co(NO3)and K4Fe(CN)6reaction products).The composite materials were characterized by FTIR,SEM,XRD.The effects of initial Cs+concentration,adsorption time,and solution pH on the adsorption effect were studied.Adsorption kinetics and adsorption isotherm models were used to study the adsorption process of HKUST-1/KCoFC on Cs+.Experiments showed that in 40 mins,the adsorption of Cs+increased rapidly,and the optimum pH for the adsorption of Cs+was 8;the adsorption process of HKUST-1/KCoFC for Cs+conformed to the pseudo-second-order kinetics and the Langmuir model.
