Abstract

Procédé de détermination en particulier d'une mesure qui est en corrélation avec la demande chimique en oxygène d'une eau ou d'une eau usée. Il consiste à vaporiser l'échantillon et à diriger la vapeur seule, sans addition d'oxygène, sur une sonde à oxygène qui détecte la pression partielle de l'oxygène libre que contient le courant d'echantillon de vapeur, d'après l'équilibre de dissociation thermique,
