Description
Traces of medicines are turning up in drinking water around the world, and the diabetes drug metformin is one of them. Abeer Aljadaani, Amr Yakout, and Hany Abdel-Aal build a sponge-like material to pull it out of water. Their material anchors copper and zinc oxide particles on treated graphene oxide sheets.
Several forces hold the drug on the surface at once: binding at the copper sites, stacking against the carbon sheets, and hydrogen bonds. Together they gave a high uptake, about 233 milligrams per gram, and the water cleared in only 25 minutes. After five rounds of cleaning and reuse, the material lost only about 4 percent of its power. It removed nearly all the drug from river, tap, and bottled water samples. The authors offer it as a strong option for treating drug-laced wastewater.
