title: Indirect atomic-absorption spectrophotometric determination of phosphorus in steel by use of the bismuth phosphomolybdate complex.
abstract: An indirect method for determination of phosphorus by atomic-absorption spectrophotometry has been developed, based on formation of the bismuthophosphomolybdate complex and its extraction by methyl isobutyl ketone. Bismuth is determined in the extract and correlated with the phosphorus content. The method is applicable to different kinds of steel.
