The presence of trace heavy metals ions in an aquatic ecosystem impacts directly or indirectly to biota and human being, which results in an increasing demand for the detection of heavy metal contaminants. This review examines recent development and current status of electrochemical detection of heavy metal ions using nanomaterials modified electrodes and discusses the sensing principles of these modified electrodes. Emphasis is given to important effect of related nanomaterials on the detection of heavy metal ions. Finally, this review outlines key challenges and opportunities with personal perspectives on the directions toward which future development and use might be directed.
