Abstract
An antimonate, such as potassium antimonate, is used as the destruction catalyst in nitrogen determinations according to the Kjeldahl principle. Preferred catalyst comprises potassium antimonate together with potassium sulfate (for increasing the boiling point of the destruction mixture) and minor amounts of zinc sulfate and cupric sulfate (as co-catalysts).
