適用范圍：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 concentrationswithin 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 detectionlimit of about 0,000 5 mg/l.
