Abstract
L'invention concerne le titrage des halogénures organiques totaux d'un échantillon liquide. On fait passer le liquide dans un lit de matière sorbante, puis on lave cette matière pour en éliminer les halogénures minéraux. On chauffe un échantillon de la matière sorbante, en atmosphère inerte, à une première température relativement basse pour vaporiser l'eau et des matières organiques volatiles que l'on pyrolyse à une deuxième température plus élevée; on chauffe le premier résidu pour en chasser des matières organiques volatiles, que l'on pyrolyse ainsi que le deuxième résidu pour transformer tous les halogénures organiques en des halogénures mesurables. Application : détermination des halogénures organiques totaux dans de l'eau.
