Abstract: Stabilized metal organic framework material (HKUST-1) is obtained by self-assembly of metal ion Cu2+ 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.
