Determination of Ultramicro Quantities of Elemental Phosphorus in Water by Neutron Activation Analysis.

Abstract

A highly sensitive method for the analysis of P4 in synthetic phossy water has been developed. The method, using a neutron activation technique, has a detection limit of 0.01 PPB fro P4. In the procedure, elemental phosphorus is first separated from water by extraction into a suitable organic solvent such as benzene. P4 is then oxidized to phosphate, which is back-extracted into the aqueous layer. The amount of phosphorus is determined by thermal neutron activation analysis. A radiochemical separation procedure is used for the separation of phosphorus-32 activity induced during the neutron activation. (author)
