Detection Methods of Mercury and Lead Ions

Abstract

Heavy metals ions are substances that can cause irreversible damage to the human body. These elements are often contained in raw materials and equipment in industrial production. These heavy metal ions, especially lead and mercury ions, can cause serious diseases when they enter the human body. Therefore, in order to avoid the excessive accumulation of mercury and lead ions in human body, it is very important to detect the heavy metal ions in products. The inductively coupled plasma mass spectrometry (ICP-MS) for detecting mercury ions has been discussed in this work. In addition, electrochemical sensor which used to detect mercury ions was also introduced in this work. As for detection of lead ions, flame atomic absorption spectrometery (FAAS) and anodic stripping voltammetry (ASV) were discussed respectively. This work will promote the understanding of lead and mercury ions detection. At the same time, more research on portable and inexpensive detection methods has become a focus of future research.
