Impedimetric sensors based on diethylphosphonate‐containing poly(arylene ether nitrile)s films for the detection of lead ions

Abstract

This article describes the elaboration and characterization of diethylphosphonatecontaining polymers coated electrodes as sensors for the detection of heavy metals traces, by electrochemical impedance spectroscopy. Diethylphosphonate groups were chosen as heavy metals binding sites. Two different series of polymers bearing these anchoring groups were synthesized. Whereas the diethylphosphonate groups
