Sponge coated with metal compound removes antibiotic from contaminated water

AI Insight

This study developed a novel adsorbent material consisting of cobalt-based zeolitic imidazolate framework (Co-ZIF) coated onto melamine sponge for removing the antibiotic azithromycin from water. The flake-like Co-ZIF structure demonstrated effective adsorption capacity in both batch and continuous flow systems, successfully removing azithromycin from aqueous solutions. The melamine sponge substrate provided structural support while the Co-ZIF coating served as the active adsorption surface for the antibiotic molecules.


Pharmaceutical contamination of water sources, particularly antibiotics like azithromycin, poses environmental and public health risks including antibiotic resistance development. This reusable, structured adsorbent offers a practical solution for water treatment facilities to remove pharmaceutical pollutants and could be scaled for real-world wastewater treatment applications.
