| Abstract: | The spectrophotometric determination of molybdenum‐containing compounds in aqueous glucose solutions using pyrazine‐2,3‐dicarboxylic acid was investigated. Determination of the molybdenum complex with pyrazine‐2,3‐dicarboxylic acid was performed at λmax = 550 nm. The light absorption of the deeply violet complex follows Lambert‐Beer's law and can be measured with a molar absorptivity in the range of 4414–9020 L mol?1cm?1. The presented method is very sensitive and shows good reproducibility for the extinction values. |
