Abstract
The preceding invention concerns a galvanic bath as well as a method for depositing a zinc-bearing layer onto a substrate surface. According to the invention, it is provided that the galvanic bath be divided into at least two cell chambers, in which the division occurs by means of a cation-exchange membrane and one cell chamber includes an acidic deposition-electrolyte and the other cell chamber includes a neutral or acidic anolyte. The acidic anolyte here is at least partially removed from the cell chamber containing it and is stripped of the foreign metal ions contained in it by means of a cation-exchange arrangement.
