chemical recovery microscopic gold

Dec 14, 2018 A team of chemists from Switzerland has developed a tool that can capture individual gold ions from water sources. It functions almost like a microscopic gold-pan. The tool is called a type of MOF, or Metal Organic Framework. In a MOF, a small set of organic molecules surround a metal atom, in this case, iron, like a cage.
