DETERMINATION OF GLYPHOSATE IN SOIL USING HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY
Abstract
The determination of glyphosate in soils is of great interest due to the widespread use of this herbicide and the need of assessing its impact on the soil. However, its residue determination is very problematic especially in soils with high organic matter content, where strong interferences are normally observed, and because of the particular physico-chemical characteristics of this polar/ionic herbicide. In this article, we improved the methodology for the analytical determination of high performance liquid chromatography using UV detectors of the widespread glyphosate herbicide used in large areas for soy or corn, including among other crops in the foothills of South -East Kazakhstan. The determination of glyphosate by the developed method can be considered as a simple, fast, efficient and sensitive method for routine analysis of this compound in soil samples that uses minimal sample handling.
