Abstract Milbury's method for the simultaneous determination of total phosphorus and total Kjeldahl nitrogen (TKN) in activated sludge has been modified for the automated determination of these constituents in surface waters, domestic and industrial wastes. Modifications were made to increase the sensitivity and to improve the accuracy for samples that contain amino acids. AutoAnalyzer I and II systems were developed with the helix digestion using a mixture of sulfuric acid, perchloric acid, and vanadium pentoxide as a catalyst. The applicable range is 0.10 to 10 mg N/l and 0.02 to 1.0 mg P/l. The phosphorus values obtained by this method on river water samples were comparable to those obtained by the U.S. Environmental Protection Agency Automated Single Reagent Method. The TKN values were also comparable to those obtained by the micro TKN method.
