Abstract

On détermine en ligne une quantité de matières dissoutes dans un échantillon liquide par des mesures de conductivité et des mesures UV. Plus particulièrement, on détermine une quantité de matières dissoutes dans une eau de traitement ou un effluent d'une usine de pâte à papier ou de papier en irradiant au moins une partie de l'échantillon liquide avec des ultraviolets, puis en mesurant l'absorption de la lumière par ledit échantillon. On mesure également la conductivité de l'échantillon liquide, puis on calcule, au moyen d'un processeur programmé à cet effet, la quantité de matières dissoutes dans ledit échantillon à partir d'une première relation entre l'absorption mesurée de la première longueur d'onde par l'échantillon liquide et la conductivité mesurée dudit échantillon.
