Lab Tests (IMAGE) Chalmers University of Technology Caption The lab tests have shown that the new method can remove more than 99 per cent of mercury from a liquid. A metal plate -- an electrode -- draws the mercury out by binding with it. The electrode consists of the noble metal platinum, and through an electrochemical process it draws out the mercury, so that an alloy of the metals is created. In this way the water is cleaned. The alloy of the two metals is very stable, meaning there is no risk of the mercury re-entering the water.
