  • Patent number: 6428676
    Abstract: This invention provides a process for the electrolytic production of metal containing solutions and in particular a high concentration low impurity low alpha lead methane sulfonate solution using a specially designed electrolytic membrane cell. The process electrolytically dissolves low alpha lead in the anode compartment of the electrolytic cell using an anion exchange membrane that separates the anode compartment from the cathode compartment. The specially designed electrolytic cell can also be used to electrolytically dissolve other metals such as tin, copper, etc. in a suitable electrolyte and membrane. The cell utilizes a two-part membrane holder having a female member and a male member, one of which is attached to the cell walls and base with a water tight seal. The membrane holder effectively minimizes contamination between the anode and cathode compartments and allows the use of inexpensive materials such as stainless steel for the cathode.
