Mitteilung: Eine Methode zur Bestimmung von Maleinsäurehydrazid
The author's method (developed in 1966) for the determination of maleic hydrazide in tobacco has been improved by the introduction of a purification step using activated carbon. Interferences produced by reactive compounds other than maleic hydrazide can thus be eliminated. The procedure proved...
