Polymer-based electrochemical sensing platform for heavy metal ions detection - A critical review

Abstract

Electrochemical sensors have the advantage of fast analysis, low cost, high sensitivity, flexible and diverse technique, and excellent adaptability for in-situ analysis. This review introduces the recent advances in the field of electrochemical sensing of heavy metal ions (HMIs) based on polymers modified electrodes. In particular, the unique properties of polymers, excellent bridging ability, absorbing ability for HMIs, different conducting polymers and composites, and highly selectively ions imprinted polymers used for the detection of HMIs are highlighted.
