Sauerstoffgehalt von reinem Wasser



Wasser kann unter gegebenen Bedingungen nur ein gewisses Maß an Sauerstoff lösen. Neben Druck und Temperatur gibt es verschiedene andere Faktoren, die die Aufnahmefähigkeit der Wassers für Sauerstoff beeinflussen; dazu zählen bei natürlichen Gewässern vor allem die darin gelösten Stoffe bzw. der Salzgehalt, der bei der Sauerstoffmessung gegebenenfalls mittels eines Korrekturfaktors zu berücksichtigen ist.

 

Tabelle: Löslichkeit von Sauerstoff in Wasser

Die nachfolgende Tabelle zeigt die maximale Aufnahmefähigkeit von Sauerstoff (100 % Sauerstoffsättigung) in reinem Wasser in mg/L bei verschiedenen Temperaturen T in °C und bei unterschiedlichen Drücken p in hPa sowie in Torr (1 Torr = 1 mm Hg = 1,333223684211 hPa).

Temperaturbereich: 0,0 °C bis 40,0 °C,

Druckbereich: 1059,91 hPa bis 933,26 hPa.
