Description

technical field [0001] The invention relates to the field of analysis and detection of heavy metals, in particular to a portable electrochemical heavy metal detection device. Background technique [0002] Electroanalytical methods (electroanalytical methods) are a type of instrumental analysis method based on the electrochemical properties of substances in solution. On the basis of the measurement relationship between electrical quantities such as current and electricity and certain quantities of the measured substance, an instrumental analysis method for qualitative and quantitative components. Electrochemical-anodic stripping voltammetry has the characteristics of extremely low cost and high sensitivity for the detection of heavy metals. Traditional heavy metal detection mostly uses atomic absorption spectrometry, atomic fluorescence method and other methods for detection. The instrument is expensive, bulky, cumbersome and requires professional personnel to operate. Ther...
