Selective Detection of Glyphosate Using Mono Nuclear Copper (II) complex with Xylenol Orange Indicator under Indicator Displacement Assay
Abstract
In this research, the mononuclear copper(II) complex with imidazole derivative ligand CuL was synthesized and characterized by standard analytical techniques. The sensing abilities towards organophosphorous pesticide was investigated using the indicator displacement assay (IDAs) approach. The results indicated that the sensing ensemble [CuL:XO] could discriminate the glyphosate from other organophosphorous pesticide and common anions. The UV-visible spectrophotometry study confirmed that glyphosate bound to CuL in a 1:1 manner. The detection limit of glyphosate was 0.11 ppm.
Keywords : mononuclear copper(II) complex ; glyphosate ; xylenol orange indicator ; indicator displacement assay
