  • Electrolysis cell
    Patent number: 4219400
    Abstract: In an electrolysis cell with anodes and cathodes which are provided with openings, the cathode chamber is separated from the anode chamber by a diaphragm. The latter consists of a porous layer of oxides or oxidic compounds of the elements of sub-group 4B of the periodic table, of aluminum, of the rare earths or of chromium. The diaphragm is applied to that side of one of the electrodes which faces the counter-electrode.

  • Removal of mercury from liquids
    Patent number: 4077856
    Abstract: In a process for the removal of mercury by treatment with elementary nickel an external voltage is applied to maintain the potential of the nickel at a value which differs from the potential of the reversible hydrogen electrode in the liquid concerned by not more than from -250 mV to +50 mV. The treatment is carried out at temperatures of from 80.degree. to 230.degree. C.
