Graphene oxide-based nanocomposite tackles antibiotic pollution in wastewater

Researchers from National Taiwan University recently investigated the use of graphene oxide (GO) within a multifunctional nanocomposite for removing veterinary antibiotics – including sulfamethoxazole, oxytetracycline, and enrofloxacin – from livestock wastewater. The team created a nanocomposite that removes 95% of these antibiotics from water, providing a sustainable tool against drug pollution and antimicrobial resistance.

The hybrid nanocomposite merges two clean-up strategies – adsorption and photocatalysis – into a single system. By integrating graphene oxide, biochar, and titanium dioxide (TiO₂), the researchers produced a porous, high-surface-area material that first attracts antibiotics and then breaks them down under ultraviolet light.
