Title
(EN) METHOD FOR MEASURING CONCENTRATIONS OF METAL ION IN ELECTRODEPOSITION SOLUTIONS
(FR) PROCÉDÉ DE MESURE DE CONCENTRATIONS D'UN ION MÉTALLIQUE DANS DES SOLUTIONS D'ÉLECTRODÉPOSITION
Abstract
(EN)
A method is provided for measuring a concentration of a metal ion in an electrodeposition solution. The method can substantially reduce the interference of organic additives and different electrode conditions on voltammetric metal ion concentration measurements.
(FR)
L'invention concerne un procédé de mesure d'une concentration d'un ion métallique dans une solution d'électrodéposition. Le procédé peut sensiblement réduire les interférences d'additifs organiques et de différentes conditions d'électrodes sur des mesures voltampérométriques de concentration d'ion métallique.
