A cool article on the C&E news website. Gold nanoparticles cleaning mercury. I worked a lot trying to clean water in graduate school. Also did a lot of ICP for metals. One problem that I frequently came up against was vaporization, and contamination of the instrument. Interestingly, adding gold helps this problem. A simple google search will yield lots of papers about this effect. Amalgams with mercury are popular for mining, dental fillings
Some mining examples mining questions and more mining
Dental amalgams are falling out of favor though it's hard to prove any link to specific health problems epa website on dental amalgams
So it makes sense that gold can be used to clean mercury. However, I enjoy reading about it and hope you do too.
