The project specifies methods for the determination of orthophosphate (see clause three); orthophosphate after solvent extraction (see clause four); hydrolysable phosphate plus orthophosphate (see clause five); total soluble phosphorus and total phosphorus after decomposition (see clauses six and seven). The methods are applicable to all kinds of water including seawater and effluents. Phosphorus contents within the range of 0,005 to 0,8 mg per litre may be determined in such samples without dilution.
