Phosphorus can be detei-mirted in iron and steels by forming phosphovanadomolybdate in perchloric-nitric acid solution and subsequently measuring the extracted yellow colour in isoamyl alcohoP or isobutyl methyl ketone 2. The latter method is limited to steels which do not contain tungsten, niobium
