Abstract A simple, sensitive, fast and inexpensive method was developed using solid-phase extraction (SPE), ultrasound and QuEChERS method with Ultra Fast Liquid Chromatography (UFLC) for trace level determination of imidacloprid in vegetables (Cabbage and Spinach) and Soil. The method was validated using Cabbage; Spinach and soil samples spiked with imidacloprid at different concentration levels (LOQ 0.01, 10 x LOQ 0.10 and 50 x LOQ 0.50 µg/g). Average recoveries (using each concentration 5 replicates) ranged from 89.39 to 99.5%, with relative standard deviations less than 2.15%, calibration solutions concentration used were in the range 0.005 - 1.0 µg/mL and limit of detection (LOD) and limit of quantification (LOQ) were 0.005 µg/mL and 0.01 µg/mL, respectively You can submit your Manuscripts at:
