适用范围：This European Standard specifies a procedure for complete digestion of raw/digested sludge, suitable for thesubsequent determination of phosphorus.NOTE Phosphorus in environmental samples can be present in many forms. This method of pre-treatment enablesthe analyst to determine all forms - i.e. total phosphorus, by quantitative oxidation yielding an aqueous solution oforthophosphate which should be analysed for phosphate according to method EN ISO 6878, EN ISO 10304~2 or anequivalent validated method.The range of the method is up to 50 g/kg P assuming appropriate dilution of the digest in the finalmeasurement step.
