Sugary Structure Has Midas Touch
Plucking gold metal out of ores and electronic waste could get more environmentally friendly, thanks to some sweet supramolecular chemistry. Chemists have discovered that α-cyclodextrin, an inexpensive cyclic compound composed of six sugar moieties, can pull gold tetrabromide salts out of solution, offering a greener method for gold recovery (Nat. Commun. 2013, DOI: 10.1038/ncomms2891).
Currently, the most popular way to extract gold involves converting . . .
