A new spectrphotometric determination of phosphorus is proposed. The method is based on the measurement of color intensity of membrane filters which are colored by the filtration of dilute molybdenum blue solutions. The proposed method is very sensitive as it can determine as low as 0.001 ppm of phosphorus. Coefficient of variation for 8 measurements of 0.1 ppm of phosphorus in 500 ml was 2.46 %. Effects of various analytical conditions were examined The method was applied to the determination of phosphorus in the sea water samples.
