A simple method for the extraction and preconcentration of pesticides such as imidacloprid, flusilazole and atrazine from soil and water
using dispersive liquid-liquid microextraction (DLLME) was described. The process was optimized by suitable selection of dispersive and
extraction solvent. The sample was extracted by methanol (dispersive solvent) containing chloroform (extraction solvent) (3:7, v/v).
Important factors such as the volume of extraction solvent, equilibration time, pH, and ionic strength were studied. pH and ionic strength
found to have, significant influence for recovery and enrichment of solute. Extraction recovery value was found to be 98, 81 and 92 %
respectively from water sample. The corresponding enrichment factor was found to be 742.01, 613.28 and 696.57 for imidacloprid,
flusilazole and atrazine, respectively. The process was applied for extraction and recovery of the pesticides from soil and water system.
Key words: Dispersive liquid-liquid microextraction; soil; water; pesticides; UV-Vis spectrophotometry
