#GoldExtraction from #EWaste gets 10 times more efficient with new sponge material
Researchers developed a nanoscale cross-dimensional composite material via self-assembly of two-dimensional graphene oxide and one-dimensional chitosan macromolecules.
By Prabhat Ranjan Mishra, Oct 27, 2024
"Researchers have developed a new type of material that’s 10 times more efficient at extracting gold from e-waste than previous adsorbents. Developed by chemists and materials scientists at the National University of Singapore, the material is a type of sponge made of #GrapheneOxide and #chitosan [shrimp shells].
"The material can reportedly transform the way gold is extracted from electronic wastes, which has been described so far as a dirty business with low yields and results in toxic #pollutants.
"The cheaper, cleaner and efficient method was tested by researchers using real e-waste provided by a recycling company."
[...]
"While the present work focused on gold, the team say the technique could be adapted to recover other valuable metals such as #silver, #platinum or #palladium from #ElectronicWaste or even #mining residues. And that is not all: as well as e-waste, the technology might be applied to a wider range of environmental cleaning efforts, such as filtering out #HeavyMetals from #PollutedWater sources or industrial effluents, reported Physics World."
