Heavy metal pollution is a serious problem in nature due to the stability of metals at contaminated sites and high toxicity to the biosphere. Lead, cadmium and zinc are major heavy metal contaminants from industrial waste streams and being continuously added to the environment. Because of the extensive use of these metals and the hazardous effect to both humans and other organisms, the development of sensitive monitoring methods has become increasingly crucial. Therefore, a simple, sensitive and accurate analytical method for the detection of heavy metal ions is necessary. In recent years, with the development of new nanoscience and nanotechnology, many nanomaterial-based electrodes have been applied for the electrochemical determination. These electrodes are beneficial and can dramatically enhance the signal intensity of an electrochemical sensor and lead to ultrasensitive detection. To the best of our knowledge, the fabrication of novel electrochemical sensors using graphene-based materials to achieve sensitive, fast and facile detection has become a hot spot, and the work herein has not been replicated elsewhere.
