Water quality. Determination of phosphorus. Ammonium molybdate spectrometric method1 Scope This International Standard specifies methods for the determination of orthophosphate (see Clause 4); orthophosphate after solvent extraction (see Clause 5); hydrolysable phosphate plus orthophosphate (see Clause 6); total phosphorus after decomposition (see Clauses 7 and 8). The methods are applicable to all kinds of water including seawater and effluents. Phosphorus concentrations within the range of 0,005 mg l to 0,8 mg l may be determined
