Analysis of antioxidant in solder plating solutions using molybdenum dichloride dioxide

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 co...

Beschreibung
Zusammenfassung:	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.
