Abstract
Quantitative analytical recoveries of soluble orthophosphate added to distilled and natural water samples at the 0.2 mg P/1 level were compared using modifications of the mixed reagent method suggested by Edwards, Molof, and Schneeman, and Murphy and Riley. The method of Murphy and Riley was shown to have the best precision and accuracy and the least bias. It is selected as the FWPCA Interim Official Method. (Author)
