DIN EN ISO 15681-1-2005 水质.用流量分析法(FIA和CFA)测定正磷酸盐和总磷含量.第1部分:流量注入分析法
Water quality - Determination of orthophosphate and total phosphorus contents by flow analysis (FIA and CFA) - Part 1: Method by flow injection analysis (FIA) (ISO 15681-1:2003); German version EN ISO 15681-1:2004
The document specifies FIA methods for the determination of orthophosphate in the mass concentration range from 0,01 mg/l to 1,0 mg/l (P), total phosphorus by manual digestion (described in ISO 6878:1998, [5, 6]) for the mass concentration range from 0,1 mg/l to 10 mg/l (P). The range of application may be changed by varying the operating conditions. This part of ISO 15681 applies 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 adaptation of the carrier and calibration solutions to the salinity of the samples.
