Competitive assay of 2,4-dichlorophenoxyacetic acid using a polymer imprinted with an electrochemically active tracer closely related to the analyte

Abstract

2-Chloro-4-hydroxyphenoxyacetic acid was used as an electroactive tracer in a ligand displacement assay involving molecularly imprinted polymer particles for the analysis of the herbicide 2,4-dichlorophenoxyacetic acid by means of linear scan voltammetry at a disposable screen-printed electrode.
