scope:
Specifies methods for the determination of - orthophosphate - orthophosphate after solvent extraction - hydrolysable phosphate plus orthophosphate - total soluble phosphorus and total phosphorus after decomposition. The methods are applicable to all kinds of water including seawater and effluents. Phosphorus contents within the range of 0,005 mg/l to 0,8 mg/l may be determined in such samples without dillution.
