Abstract: In the present study, the precision and accuracy of portable X-ray fluorescence spectroscopy (PXRF) in heavy metal (Cr, Cu, Zn, As, Pb and Ni) determination in six typical soils were investigated to reveal its feasibility. It was shown that under the premise of processing, the determination precision of heavy metals in 6 typical soils by PXRF method was within 0.14% and 11.40%. By taking the results of inductively coupled plasma optical emission spectrometry (ICP-OES) method as reference, the determination accuracy of PXRF method in 5 typical soils was within 75% and 125%, which could meet the requirements of rapid determination of heavy metals in soil, but the accuracy of Cr and low concentration of As in latosol was low by PXRF method, which could not meet the requirement and should be further improved.

Key words: soil, heavy metal, rapid determination
