The purpose of this study was to develop and evaluate a procedure capable of converting all the phosphorus in a natural water sample to measurable phosphate. The experimental procedure consists of the combined oxidation and hydrolysis of the sample in an acid medium, followed by the colorimetric determination of phosphate. The meta‐ and pyrophosphates present are hydrolyzed to the orthophosphate. The organic phosphates are split off and made available for colorimetric analyses.
