Abstract
A method of and apparatus having utility in an electrodialysis and electrosynthesis process energized by direct eletrical current for the purification and replenishment of an electroless copper plating solution comprises indirectly measuring the hydroxide production that is put into and left in the electroless copper plating solution from a catholyte solution in which the hydroxide is synthesized by measuring the net hydronium ion content of an anolyte solution into which waste products from the electroless copper plating solution are transported, and adjusting the flow of direct electrical current in response to the net hydronium ion production in the anolyte solution.
