Polarographic determination of phosphorus

Talanta, 1983
A method has been developed for the determination of phosphorus, as phosphate, by means of the catalytic polarographic wave for the reduction of hydrogen peroxide in the presence of Mo(VI). This reduction is combined with the previous formation and extraction of 12-molybdophosphoric acid.

THE DETERMINATION OF PHOSPHOLIPID PHOSPHORUS

Canadian Journal of Research, 1949
A simple accurate method for the determination of phospholipid phosphorus is described. Conditions for the digestion of phospholipid have been developed permitting the utilization of a colorimetric procedure for inorganic phosphorus that is characterized by excellent color stability and strict adherence to Beer's law over a range of 0 to 65 μgm.

Substoichiometric determination of phosphorus

Journal of Radioanalytical Chemistry, 1981
Phosphorus in orchard leaves (NBS SRM-1571) and spinach (SRM-1570) was determined by various substoichiometric analytical methods such as the direct method, GRASHCHENKO's method and the method of carrier amount variation. All samples were labelled with32P radioisotope. The data obtained by the method of carrier amount variation were also treated by the

Determination of Radioactive Phosphorus

Journal AWWA, 1965
A solvent extraction method was recently proposed for the determination of radiophosphorus in mixtures of radionuclides. This method is rapid and free of interference from other radionuclides. It is used as the basis for the procedure described in this article for the determination of radiophosphorus in water.
