#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."

dm Schaumfestiger ist nicht #vegan 😧

Ich hatte den letztens gekauft, weil ich eine Alternative zum Rossmann Schaumfestiger probieren wollte (ihr kennt das, wenn man hartnäckig das selbe Produkt kauft, wird es bald eingestellt).

Da es ebenso eine #Eigenmarke ist, hab ich ähnliche Zusammensetzung (mglw. gar selben Hersteller) erwartet.

Beim Austauschen fiel mir auf, daß der #Rossmann Schaumfestiger vegan ist und der von #dm … nicht O.o

#Codecheck offenbarte dann #Chitosan aus Garnelenschalen 🤢

It's possible that someone has just invented the next revolution in battery design. Called chitosan, it's found in crab and lobster shells.

Oh interesting, apparently #chitosan can be made from #fungi: https://www.sciencedirect.com/science/article/pii/B9780128179703000146

(but it's not widely available yet).
