Gold, a known electrical conductor, is widely used in electronic products, so it is of great importance to recover gold from e-waste. However, high extraction capacity and precise selectivity are still difficult to achieve if small amounts of gold are mixed with other metallic elements.

A group of scientists from Tsinghua University, the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, the Metal Research Institute of the Chinese Academy of Sciences and the University of Manchester found that a material made of reduced graphene oxide has a high ability. to extract traces of gold from electronic waste.

According to the study, this graphene material can precisely extract gold from e-waste without adsorbing other metallic elements and without the use of other materials or additional energy.

The scientists also developed a gold adsorption method based on graphene films that is suitable for large-scale production and allows the efficient and continuous extraction of gold resources from electronic waste.

The method involves the use of commercial graphene oxide, which is very cost-effective. Thus, a new solution was proposed for the sustainable development of gold resources and e-waste recycling.

As reported by Ukrinform, researchers from the Methane Institute of the Ministry of Agriculture and Rural Affairs of the People’s Republic of China have discovered single-celled microorganisms that obtain energy through the oxidation of waxy hydrocarbons.
