What is Indirect Determination of Phosphorus by Non-dispersive Atomic Fluorescence Spectrometry of Antimony about?
Phosphate is converted to molybdoantimonylphosphoric acid, which is reduced and extracted into isobutyl acetate. The extracted material is atomized in a graphite furnace and antimony determined by non-dispersive atomic fluorescence spectrometry. The detection limit is 2 ng of phosphorus, limited by the reagent blank, and the linear analytical range covers three decades of concentration up to 2 pg. The technique is applied to the determination of phosphorus in a phosphosilicate glass fii deposited on a silicon wafer. The indirect method for the determination of phosphorus based on the formation of 12molybdophosphoric acid is useN in atomic absorption spectrometry, In this technique, phosphate is determined by extracting 12molybdophosphoric acid into a suitable solvent and measurin g the molybdenum content in the extract [l-4].
