Abstract:
A process is described wherein hydrogen and its isotopes are dissolved in palladium metal in high density by utilizing electrochemical methods in an electrolytic cell. The cell has an inert anode and a palladium containing cathode, both being immersed in an electrolyte which contains a lithium salt dissolved in an aprotic solvent, and a small amount of water. The dissolved hydrogen to palladium ratio in the palladium bearing cathode, which may be achieved by this process, is in excess of 0.95.
Abstract:
Electrodes are disclosed which comprise a porous conductive material as a primary electrode component in electrical contact with a secondary electrode component which preferably is a metal, such as titanium. The secondary electrode component is normally conductive when operating as a cathode, and is capable of alternating between being non-conductive when operating as an anode and becoming conductive again when the electrode is operating as a cathode. Processes for removing metallic species from solution utilizing such electrodes are also disclosed.
Abstract:
Apparatus usable in the electrolytic treatment of electroactive species in a solution include a porous electrode which is supported across a fluid flow path in such a manner that fluid flowing along the flow path must pass through an effective portion of the electrode.
