ABSTRACT:
The present invention relates to antioxidant analysis for solder plating solutions, by using a complexing solution comprising a molybdenum compound, such as MoO2Cl2, to form a highly colored antioxidant-molybdenum complex, which can be detected and analyzed by UV-Vis spectroscopic, as a basis for concentration determination for the antioxidant.
