Bibliography
Provides flow injection analysis (FIA) methods for the determination of orthophosphate in the mass concentration range from 0,01 mg/l to 1,0 mg/l (P), and total phosphorus by manual digestion in accordance with ISO 6878 for the mass concentration range from 0,1 mg/l to 10 mg/l (P). Applicable to various types of water (such as ground, drinking, surface, leachate and waste waters).
