Abstract

In this research, the best method for extraction Dimethoate pesticide from agricultural soil samples taken from greenhouses in the Burj Islam area located in Lattakia Governorate was determined, in addition to determining the appropriate wavelength for analysis using a high-performance liquid chromatography.

The results of the analysis, using different mixtures of solvents (hexan:aceton – double distilled water:methanol- methanol:dichloromethane- double distilled water) showed that the best mixture was( hexane: acetone 1:1) by applied two extraction methods Ultrasonic-Soxhlet, the Ultrasonic waves were the best, as the analysis was performed with different wavelengths (240 - 225 - 205 - 200) nm, the best of which was (200 nm) . The recovery ranged between 99,47 and 106,38%, The limits of Detection (LOD) are 0,02 ppb , and the limit Quantitative Detection (LQD) are 0,068 ppb.
