Abstract
AbstractA method is described for the measurement of simazine [2‐chloro‐4,6‐bis(ethylamino)‐1,3,5‐triazine] residues in chickpeas (Cicer arietinum). Ground chickpea samples were extracted with dichloromethane, followed by clean‐up on alumina. Gas‐liquid chromatography using metribuzin [4‐amino‐ 6‐tert‐butyl‐4,5‐dihydro‐3‐methylthio‐1,2,4‐triazin‐5‐one] as internal standard with thermionic detection was used to quantify simazine residues. The limit of detection was 0.02 mg kg−1 and the recoveries of simazine from chickpea samples (0.1–4 mg kg‐1) averaged 92%.
