Method 365.1, Revision 2.0: Determination of Phosphorus by

DETERMINATION OF PHOSPHORUS BY AUTOMATED COLORIMETRY 1.0 SCOPE AND APPLICATION 1.1 This method covers the determination of specified forms of phosphorus in drinking, ground, and surface waters, and domestic and industrial wastes. 1.2 The methods are based on reactions that are specific for the orthophosphate ion.

Understanding Phosphorous - Environmental Express, Inc.

The color developing reagent for phosphate determination has a very short lifespan. It is only stable for a maximum of 4 hours. There is a method that allows you to have two separate reagents that are stable for weeks to months and then add them in separate amounts to the sample for color development.
