Water quality - Determination of phosphate and total phosphorus contents by flow analysis (FIA and CFA) - Part 1: Method by FIA

This International Standard describes CFA and FIA methods for the analysis of orthophosphate in the range of 0,01 mg/l to 1,0 mg/l (P) and total phosphorus (by manual digestion or with an integrated UV digestion) in the range of 0,1 mg/l to10 mg/l (P). The range of application may be changed by varying the operating conditions. This method is applicable to the analysis of seawater, but with changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of samples.
