Determination of phosphorus in natural waters with the aid of extraction of the phosphorus-molybdenum heteropolyacid with butyl alcohol

Abstract

1. In the determination of phosphorus in natural waters, extraction of phosphates in the form of the phosphorus-molybdenum heteropolyacid makes it possible to avoid the introduction of salt corrections. 2. The extraction method can be used in cases in which the determination of phosphates in natural waters is impossible by the Denige-Atkins method. 3. In the determination of total phosphorus content, the extraction method is more accurate than the Denige-Atkins method.
