Residue Determination of Prometryne and Acetochlor in Soil and Water by High Performance Liquid Chromatography

Abstract:

A new method has been developed to detect the residues of the binary mixed pesticides of prometryne-acetochlor in soil-water system by high performance liquid (HPLC). The study compared two pre-treatment ways: direct injection and solid-phase extraction. The results showed that the method of direct injection is better than that of solid-phase extraction. In the linear from 0.35 μg·mL^-1 to 15 μg·mL^-1 of prometryne-acetochlor, the correlation coefficients for prometryne and acetochlor were 0.9993 and 0.9999, and the limits of quantification were 0.011 μg·mL^-1 and 0.106 μg·mL^-1 respectively. The recoveries ranged from 91.2% to 109.7% with the relative standard deviations of 0.42% -0.78%. This method provides a dependable approach to determine the residues of prometryne and acetochlor in the soil-water system.
