摘　　要：以均苯三甲酸为配体,与金属离子Cu^2+自组装得到稳定的金属有机框架材料(HKUST-1),利用该材料吸附水体中的砷(V),并借助原子荧光光度计进行检测。结果表明,在pH=11、振荡时间为180 min时,其最大吸附量Qe=88.6mg/g,经后期拟合,该反应符合拟二级动力学和Langmuir等温吸附模型。该研究成果在一定基础上拓宽了金属有机框架材料的应用。Stabilized metal organic framework material (HKUST-1) is obtained by self-assembly of metal ion Cu^2+ with trimesic acid as ligand.Arsenic (V) in water is absorbed by this material,which is detected by atomic fluorescence spectrometer.The results show that the maximum adsorption amount of arsenic is 88.6 mg·g^-1 when pH=11 and time is 180 min.After fitting,it is found that the reaction accords with pseudo-secondary kinetics and Langmuir isotherm adsorption model.This research progress broadens the application range of metal organic framework materials on a certain basis.
