    A simple and rapid solid-phase extraction (SPE) supported Gas Chromatographic-Electron Capture Detection (GC-ECD) method has been presented for the routine determination of atrazine in some common agricultural produces. Equivalent to USP G-42 GC stationary phase, DB-35 ms capillary column and ECD detector was selected on the basis of physical and structural characteristics of atrazine. Temperature programming of 20 minutes with 0.8 mL/min optimized gas flow gave maximum number of the theoretical plates (N=104) and high resolution (Rs~2.1 min) with LOD and LOQ values of 0.001 μg/L and 0.1 μg/L respectively. LOQ achieved by the present method is almost below the maximum residue levels recommended by the European legislation. Satisfactory spiked recoveries of the atrazine were obtained from agricultural produces ranging from 82.2 to 97.8% with relative standard deviations below 3.8.. View More»
