Magnetic Porous Material Derived from Ni-MOF for the Removal of Tetracycline from Aqueous Solution
Source abstract
Abstract
The efficient removal of antibiotic residues from aqueous solution is very important for water security. Studies have found that adsorption is widely used for the removal of antibiotics due to its cost-effectiveness, low energy consumption, simplicity of operation, and environmental friendliness. In this study, a novel magnetic porous carbon adsorbent (Ni-MPC-400) with a high adsorption capacity and saturation magnetization was synthesized via direct carbonization of Ni-MOF at 400 °C pyrolysis temperature and used to efficiently remove tetracycline from an aqueous solution. Adsorption experiments showed that Ni-MPC-400 exhibited excellent tetracycline adsorption capacity (441.51 mg·g –1 ) from the aqueous solution. Possible adsorption mechanisms were proposed through characterization and analysis. The adsorption mechanisms mainly involved π–π interactions, hydrogen bonding, metal–organic complexation, and pore filling effects. In addition, Ni-MPC-400 showed rapid and sufficient adsorption at a low concentration of tetracycline (5 mg·L –1 ) and good adsorption performance over a wide pH range. In addition, the material has been tested to have good immunity to interference and regenerative capacity, demonstrating a potential application in the removal of tetracycline contaminants from aqueous solutions.
