Description

An isotope exchage method for the speciative determination of phosphorus (PO43-,PO33- and total P) in natural water samples is proposed by using the exchange system of molybdophosphate in the aqueous phase and tetraphenylarsonium molybdophosphate in the organic phase. In this exchange system, only PO43- exchanges and is determined. When the sample water is treated with Br2 water in advance, the amount of PO43-+PO33- can be obtained. When the sample is treated with H2SO4 and HNO3, the amount of total P can be determined. (author) 4 refs.; 5 tabs
