Montmorillonite-loaded copper sulfide for the removal of tetracycline hydrochloride from aqueous solutions
Scientists created a new material that can remove tetracycline (a common antibiotic) from water sources like rivers and lakes with nearly 100% effectiveness.

The new water-cleaning material could help protect drinking water and reduce health risks from antibiotic pollution.
