Abstract (en)
[origin: CA1166187A] A method for determining current efficiency in a galvanic bath employs a measuring cell within which a sample is introduced from the galvanic bath. In this sample, onto a preferably rotating electrode metal is precipitated. A negative voltage is applied at constant current during a first predetermined time during the precipitating. Thereafter, the precipitated layer is anodically eroded by use of a suitable electrolyte solution upon pole-reversal of the DC voltage. The current efficiency is then calculated.
