Qualité de l’eau — Dosage du calcium et du magnésium — Méthode par spectrométrie d’absorption atomique
| Published By | Publication Date | Number of Pages |
| ISO | 1986-05 | 8 |
La présente Norme internationale spécifie une méthode de dosage du calcium et du magnésium dissous par spectrométrie d'absorption atomique.Elle est applicable à l'analyse des eaux brutes et des eaux de boisson et peut être utilisée directement pour des eaux contenant jusqu'à 50 mg/l de calcium et 5 mg/l de magnésium. Pour des échantillons de plus forte concentration en calcium et en magnésium, un plus petit volume de l'échantillon doit être prélevé pour l'analyse.Lorsqu'on utilise une flamme air/acétylène et le facteur de dilution 1 à 10, comme décrit en 6. 1, la gamme optimale est de 3 à 50 mg/l pour le calcium et de 0,9 à 5 mg/l pour le magnésium.
