Further to my earlier email,
Europium in old gadgets
The idea comes from Marie Perrin, a doctoral chemist at ETH Zurich, who discovered a shortcut for prying europium out of discarded fluorescent lamps.
Her tweak replaces the hundred plus solvent extractions usually needed for the job with one quick reaction.
“Rare earth metals are hardly ever recycled in Europe,” noted Victor Mougel, professor of inorganic chemistry at ETH Zurich.
