The document describes the determination of phosphorus compounds present in ground, surface (including sea waters) and waste waters in various concentrations in the dissolved and undissolved state. Phosphorus concentrations within the range of 0,005 to 0,8 mg/l can be determined in samples without dilution, and with an extraction procedure can be determined smaller phosphorus concentrations (up to 0,0005 mg/l).
