Magnetite nanoparticles recover copper waste from whisky manufacturing process
During its production whisky is distilled. Using copper stills for this process is important for developing the flavour and character of the whisky. However, a considerable amount of copper leaches into the whisky – manufacturers must remove this before the whisky is aged and bottled.
Researchers have recently discovered a new way to remove the copper that also allows it to be recycled. The copper is absorbed onto magnetite nanoparticles that can then be separated out using a magnet. The copper is then recovered and used as a catalyst in reactions to produce a wide array of products from polymers to pharmaceuticals.
