Zusammenfassung

Molybdoheteropolygelb wird mit Methylpropionat extrahiert. Eine Störung durch Silicium wird dadurch eliminiert, daß die entsprechende Si-Heteropolyverbindung nicht mitextrahiert wird. Mikromengen Phosphor können rasch und genau nicht nur in Abwasser, sondern auch in Flußwasser bestimmt werden. Die Nachweisgrenze liegt bei 0,5 ppm; der Variationskoeffizient beträgt 4,7%.

Summary

Microamounts of phosphorus are determined in waste water by HPLC. The method is based on the solvent extraction of molybdoheteropoly yellow with methyl propionate. The corresponding silicon compound is not extracted into this solvent. Thus, the interference by silicon is excluded. Microamounts of phosphorus can be determined not only in waste water but also in river water rapidly and exactly. The limit of detection is 0.5 ppm, the coefficient of variation 4.7%.
