A method for rapid detection of heavy metals in soil and its application

Rapid detection of heavy metals in the soil and getting their distribution is important for heavy metal pollution prevention and control. This paper proposes a rapid detection method based on energy dispersive X-ray fluorescence spectroscopy, which uses modular components to implement the detection system. This method has been used to measure heavy metal levels of Cr, Zr, Zn, As, Pb in the standard materials of several soil samples. The experimental results show that this method has the advantage of fast analysis, simple sample preparation, easy carrying, and non-destructive characteristics. It is ideal to meet the requirements of timeliness and accuracy of screening for heavy metals in soil and in-situ measurement.
