A gas chromatographic (GC) method is described for the determination of maleic hydrazide residues in potato tubers by oxidation of maleic hydrazide with aqueous lead dioxide to 3,6-pyridazinedione in the presence of cyclopentadiene. The reaction product, a volatile Diels-Alder adduct, could be detected in potatoes at levels in excess of 0.05 ppm with an electron capture detector. Recoveries of maleic hydrazide (as the Diels-Alder adduct) from potatoes at fortification levels of 0.1 to 10 ppm averaged 91.7%.
本文描述了一种气相色谱（GC）方法，用于测定马铃薯块茎中的马来酰肼残留量。该方法是在环戊二烯存在的情况下，将马来酰肼用二氧化铅水溶液氧化为3,6-哒嗪二酮。反应产物是一种挥发性的狄尔斯-阿尔德加成物，使用电子捕获检测器可检测到马铃薯中含量超过0.05 ppm的该加成物。在0.1至10 ppm的强化水平下，从马铃薯中回收的马来酰肼（以狄尔斯-阿尔德加成物形式）平均回收率为91.7%。
