Electrolytic cell for recovering metal from solution |
摘要 |
<p>An electrolytic cell (2) for the recovery of silver from a photographic fixer solution has a cylindrical cathode (14) secured to and depending downwardly from a screw-on lid (6) of the cell into the solution. The cathode is formed from a sheet of graphite foil laminated to a polyester base, and is clamped at its upper periphery around a boss (26) of the lid. A metal connection ring (22) is embedded around the outer periphery of the boss and is contacted by the cathode. This arrangement is particularly suitable for allowing a thin, flexible disposable cathode to be conveniently removed from the cell by means of the lid, without the user being exposed to contact with the silver or with the solution. <IMAGE></p> |
