Mercury deposited in amounts of the order of a few monolayers on Pt, Fe, Ni and Co raises the overvoltage of hydrogen evolution in alkaline solution. On Cr it deaeases and on MO it has little influence, but these metals corrode in alkali. the overvoltage R&mn&Le mercure deposal en quantit&s de l'ord

The removal of mercury from smooth mercury poisoned platinum electrodes by means of simultaneous hydrogen evolution is described. It is caused by volatility of mercury and its evaporation into the stream of electrolytically discharged hydrogen. The kinetic equation for this process is derived and li
