    The mechanism of elution of gold cyanide from activated

    The presence of spectator cations (M n+) enhances the formation of M n+ {Au(CN) 2 } n ion pairs on the carbon, which in turn suppress the elution of gold cyanide. The dynamics of removal of these cations determine the horizontal position of the gold peak in an elution profile.
