    摘要: The present invention relates to a method for determining concentration of brightener and leveler contained in an aqueous acid metal electroplating solution, by firstly determining the concentration of the brightener at a first set of measurement conditions, and secondly determining the concentration of the leveler at a second set of measurement conditions, provided that the first set of measurement conditions differ from the second set of measurement conditions on the rotation speed of a rotating disc electrode used for measuring plating potential of said aqueous acid metal electroplating solution, and optionally, the electroplating duration at which the plating potential of said aqueous acid metal electroplating solution is measured, provided that the first rotation speed is lower than the second rotation speed, and that the first electroplating duration is shorter than the second electroplating duration.
