Description

Pamela Cinfrignini and co-authors design water based gels that pull gold out of waste water in a 2024 study. The gels, called hydrogels, can soak up toxic compounds from water. For metals, recovery matters both to protect nature and to recycle a scarce, costly resource. Gold is in high demand for many technologies.

Their gel is made from two common building blocks and is easy to prepare. In acid water at room temperature, the gel turns gold ions into solid gold particles. Batch tests took up as much as 124 milligrams per gram and separated gold well from five other precious metals in a mix like real factory waste. The gel could also serve for waste from old electronics.
