Abstract:

Samples, of average weight less than 100 micrograms, are decomposed in a sulphuric-perchloric acid mixture in an open tube. The quantity of phosphate formed is measured by the absorbance of the phosphovanadomolybdate complex at 315 micrograms. Results are usually within or - 0.3 absolute of the calculated value. Solids and involatile, non-hygroscopic liquids, some containing Br, F, N or Si, were successfully analysed, but some fluorinated compounds resist acid attack. Advantages and disadvantages of the determination of phosphate by Uv absorption are discussed. Author
