適用范圍：The document specifies CFA methods for the determination of orthophosphate in the mass concentration range from 0,01 mg/l to 1,00 mg/l (P), and total phosphorus in the mass concentration range from 0,10 mg/l to 10,0 mg/l (P). The digestion of organic phosphorus compounds and the hydrolysis of inorganic polyphosphate compounds is performed either manually (described in ISO 6878, [5, 6]) or with an integrated UV digestion and hydrolysing unit. The range of application may be changed by varying the operating conditions. This standard is applicable to various types of water (such as ground, drinking, surface, leachate and waste water). This method is as well applicable to the analysis of seawater, but with changes in sensitivity and after adaptation of the carrier and calibration solutions to the salinity of the samples.#,,#
