Abstract This paper presents a brief review of detecting heavy metal ions using various nanomaterial modified
electrodes by all kinds of electrochemical methods. The characteristics of different nanomaterial modified electrodes
were analyzed and the important application of carbon materials, metal materials and biological materials
and other nanomaterial modified electrodes in heavy metal ions detection were emphatically introduced. Finally,
the research status of nanomaterial modified electrodes in the detection of heavy metal ions was summarized and
the future development of nanomaterial modified electrode in the detection of heavy metal ions is prospected.
