The effect of CaCO 3 -Ni-MOF synthesized by different ratio between Ni 2+ and organic ligand terephthalic acid on the removal of heavy metal ions was studied. CaCO 3 -Ni-MOF was synthesized by ultrasonic and solvothermal methods. The crystal structure and morphology of the material were characterized by XRD and SEM. TG curve was used to test the thermal stability of the material. In addition, the experimental study also found that CaCO 3 -Ni-MOF can remove heavy metal ions. The adsorption capacity of Cu 2+ was found to be 16.96mg/100mg by energy spectrum analysis. And the amount of lead also has a certain amount of adsorption. The results show that the performance of the CaCO 3 -Ni-MOF material in the water environment has not been destroyed, and the heavy metal ions in the water can be effectively separated.
