Abstract
Copper metal is involved in many industries and is known for its adverse impacts on human health and the environment. The metal–organic framework (MOF) is now a rise-up method for wastewater treatment. A novel structured MOF was prepared and characterized using SEM, EDAX, XRD, and FTIR to confirm its structure then used for copper removal. A series of experiments were designed. Synthetic solutions with different copper ion concentrations were prepared. These solutions were adjusted under different pHs (5, 7, and 9). A standard weight of MOF 0.05 gm was used. The results showed that the different characterization techniques confirm the MOF structure. MOFsuccessfully removed copper ions with removal rates of 94.6%, 93%, 91.5%, and 92.5 % for the synthetic solution's concentration 5, 10, 15 and 20 ppm respectively. For pH experiments, the MOF showed a well-defined ability to remove copper under pH 5 and 7 rather than pH 9.
