Kurzfassung:
A gas chromatographic method is described for direct determination of carbetamide residues in rape and soil. Rapeseed, leaves and stem of rape, and soil samples are extracted with acetone and the extracts are cleaned up by coagulation and partition with petroleum ether, followed by extraction with dichloromethane. Carbetamide is determined by gas chromatography using a nitrogen-phosphorus detector. Recovery ranges for rapeseed, leaves and stem of rape, and soil samples fortified with 0.1-10 ppm carbetamide were 91.4-103% [average 97.2 ± 12% (n = 9)], 94.4-102% [98.2 ± 4.4% (n = 12)] , 87.9-93.9% [91.2 ± 6.5% (n = 9)1, and 86.7-102% [94.5 ± 4.5% (n = 15)], respectively.
