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
## Abstract A method for the determination of silicon in steels as the molybdenum blue complex is described. By the use of n number of alternative acid solvent mixtures, the method extends the range of steels which can be analysed by existing procedures. A new reducing agent, a mixture of ferrous s
