11-Molybdobismuthophosphate - a new reagent for the determination of ascorbic acid in batch and sequential injection systems
2010
Abstract
The guanidinium salt of the new heteropolymolybdate was synthetized, characterized and used as a reagent for batch spectrophotometric and sequential injection determination of ascorbic acid. The proposed method was successfully used for the determination of ascorbic acid in pharmaceuticals and fruit juices, and the results were in good agreement with 2,6-dichlorophenolindophenol method.
