Gold extraction from e-waste 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.
Developed by materials scientists at the National University of Singapore, the material is a type of sponge and 10 times more efficient at extracting gold from e-waste.
They developed a nanoscale cross-dimensional composite material via self-assembly of two-dimensional graphene oxide and one-dimensional chitosan macromolecules, capable of acting simultaneously as a scavenger of gold ions and as a reducing agent, according to the study. They maintained that this innovation in gold recovery not only enhances efficiency and sustainability but also marks a significant advancement in developing eco-friendly solutions for managing e-waste and conserving natural resources. 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 heavy metals from polluted water sources or industrial effluents, reported Physics World.
