SS-EN-ISO-6878 › Water quality - Determination of phosphorus - Ammonium molybdate spectrometric method (ISO 6878:2004)
The following bibliographic material is provided to assist you with your purchasing decision:
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 in such samples without dilution. A solvent extraction procedure allows smaller phosphorus concentrations to be determined with a detection limit of about 0,000 5 mg/l.
