Bibliographie

La présente norme européenne spécifie trois méthodes différentes (méthodes A, B et C) de dosage du soufre présent dans les extraits d'engrais sous forme de sulfate. La méthode A utilise la gravimétrie. La méthode B emploie la spectrométrie d'émission optique à plasma inductif (ICP-OES). La méthode C a recours à la chromatographie ionique (IC).
