Abstract

L'invention est relative à un procédé pour le dosage d'acide nitrique dans des mélanges contenant de l'eau ou d'autres acides, ou encore dans des nitrates solides ou des mélanges de ceux-ci avec d'autres substances solides après leur dissolution dans de l'eau et après la libération de l'acide nitrique par l'addition d'acide sulfurique, caractérisé en ce que l'on fait réagir l'échantillon, se presentant sous forme de solution, avec un composé chimique facile à nitrer et en ce que l'on mesure la chaleur dégagée au cours de cette réaction et on évalue celle-ci en tant que mesure de la quantité d'acide nitrique présent dans l'échantillon examiné.
