Molecularly imprinted copolymer/reduced graphene oxide for the electrochemical detection of herbicide propachlor

Abstract The toxicity of propachlor (PROP) with its chloroacetanilide members is reported. Rapid and sensitive detection PROP critical for ecotoxicity evaluation the removal process. A novel voltammetric sensor developed based on imprinted poly (o-phenylene diamine-co-pyrrole) (o-PD-co-Py) electrochemically reduced graphene oxide (ERGO) to detect at a trace level. use ERGO provides high density cavities better sensitivity. layer improves selectivity sensor. electrode modification was characterized by scanning electron microscopy electrochemical approaches. working parameters were investigated optimized. redox behavior an external probe [Fe(CN) 6 ] 3?/4? recorded as signal selective binding. proposed presented wide linear responses logarithmic concentrations from 0.1 pM µM LOD 0.08 pM. sensor’s against some interference demonstrated. This applied successfully in spiked water (lake tap), red tea, soil samples good recoveries reasonable RSD % values. Graphical abstract
