20-litre reactor (IMAGE)
Caption
The method developed by Chalmers for removing mercury from water or chemicals uses electrochemistry. The toxic metal is taken up by an electrode coated with the metal platinum. The electrode binds the mercury to itself by the two metals forming an alloy. Once the mercury is in solid form, it is easy to remove from the electrode in a safe and energy-efficient way. The electrode can then be reused. The photo was taken at an experiment at Chalmers and shows a 20-litre reactor.
