Fabrication and Application of Electropolymerized Molecularly Imprinted Film for 3-Phenoxybenzoic Acid Detection

This study aimed to develop a rapid and precise method for detecting 3-phenoxybenzoic acid (3-PBA) in
environmental samples which can provide technical support for ecological risk assessment of the major pyrethroid
metabolite. Using o-aminophenol (OAP) as the monomer and 3-PBA as the template, a molecularly imprinted membrane
(MIM) for 3-PBA detection by combination with electrochemical technology was formed on the surface of glassy carbon
electrode (GCE). The response to 3-PBA was completed in 30 s. The results showed that the relationship between peak
current and 3-PBA concentration within the range of 2.00 mg/L to 11.00 mg/L was linear (the linear equation was y = 0.29x +
2.16) with a linear correlation coefficient of 0.99 and the limit of detection (LOD) was 1.47 mg/L. The recoveries were
between 92.00% and 101.00% in spiked water samples.
