Abstract

Abstract:

A novel molecularly imprinted electrochemical sensor for 2,4-dichlorophenol(2,4-DCP) detection was fabricated on the surface of gold electrode by self-assembly of o-aminothiophenol(oATP) and electropolymerization of oATP/Au nanoparticles in the presence of template molecule. The modification procedure was characterized via cyclic voltammetry and electrochemical impedance spectroscopy. In the presence of K₃Fe(CN)₆ as redox probe, the peak current of K₃Fe(CN)₆ decreased linearly with the increasing concentration of 2,4-DCP from 5.0×10^-8 to 1.2×10^-4 mol/L(R²=0.9964) with a detect limit of 1.5×10^-8 mol/L(S/N=3). Three chlorophenols possesing analogous structures, including 2,6-DCP, 2,4,6-trichlorophenol(2,4,6-TCP) and pentachlorophenol(PCP) were chosen to examine the specific recognition ability of the imprinted sensor. The results showed that MIP electrode had the highest current response toward 2,4-DCP. In addition, the feasibility of its practical applications has been demonstrated in the analysis of four water samples with the recoveries ranged from 95.2% to 109.3%.
