Abstract

OF the several colorimetric methods for the determination of phosphorus which have been described during recent years, probably the Briggs [1922] modification of the Bell and Doisy [1920] method and the method of Fiske and Subbarow [1925] have met with most general favour. Both these methods depend on the reduction of phosphomolybdic acid to give a blue colour, the intensity of which is proportional to the concentration of phosphate.
