Electrochemical Analysis of Heavy Metal Ions Using Conducting Polymer Interfaces

Conducting polymers (CPs) are highly conjugated organic macromolecules, where the electrical charge is transported in intra- and inter-chain pathways. Polyacetylene, polythiophene its derivatives, polypyrrole polyaniline among best-known examples. These compounds have been used as electrode modifiers to gain sensitivity selectivity a large variety of analytical applications. This review, after brief introduction electrochemistry CPs, summarizes application CPs’ interfaces towards heavy metals’ detection using potentiometry, pulse anodic stripping voltammetry, alternative non-classical electrochemical methods.
