| Summary: | A new indirect AAS method using the bismuth phosphomolybdate complex for the
determination of phosphorus in foodstuffs is suggested. The bismuth
phosphomolybdate complex in acid medium was extacted with isobutyl
methylketone and the phosphorus was determined through bismuth in an
air/acetylene flame by utilising the 223.06 nm resonance line of bismuth. The
interference caused by antimony and titanium can be neglected in the presence
of excess of bismuth. The detection limit of the method is 0.008 mg/mL of
phosphorus. |
