Phosphorus Speciation in Water and
Spivakov, T.A. Maryutina, and H.
Abstract: Environmentally significant phosphorus species in
water and phosphorus fractions in sediments are briefly discussed and
the methods for their determination are described. One of the most critical
analytical steps is the separation of the different forms which, after
conversion into orthophosphates, may be determined by a multitude of
various techniques. Spectrophotometric methods are often preferred for
routine analysis. Several rapid automatic methods for the separation
and determination of orthophosphate, linear polyphosphates, cyclic condensed
phosphates and lower oxidation state anions of phosphorus, which may
exist in natural and waste waters, have been developed. They are mainly
based on the use of flow-injection analysis, high-performance liquid
chromatography including ion chromatography, capillary electrophoresis
and a few of other techniques. These methods have been described and
