Scientists develop MOF nanomaterial to remove antibiotics in water

(Nanowerk News) Chinese scientists have developed a kind of nanomaterial that can effectively remove antibiotics in wate (Applied Surface Science, "High-efficiency adsorption of norfloxacin using octahedral UIO-66-NH2 nanomaterials: Dynamics, thermodynamics, and mechanisms")r.
Antibiotic residues are new kinds of water pollutants that can lead to antibiotic resistance, posing a great threat to the ecological environment and human health.
Researchers from the Hefei Institutes of Physical Science successfully synthesized highly stable amino-functionalized Zr-based metal–organic frameworks (UIO-66-NH2) and studied the adsorption behaviors of norfloxacin (NOR) in water.
The adsorption capacities of UIO-66-NH2 reached a maximum of 222.5 mg/g for NOR, which were considerably higher than that of most reported adsorbents.
The material has a high adsorption capacity and can be recycled. It can remove antibiotics without secondary pollution. Researchers also revealed the absorption mechanism of the material.
The research provides new perspective for the removal of antibiotics in water by nanomaterials and has broad application prospects.
