Abstract：Inorder to improve the detection accuracy of low concentration heavy metals in groundwater around industrial parks，taking heavy metal Pbasan example，Chlorella pyrenoidosa wasselected as anadsorbent to enrich Pb ，and an efficient detection method of heavy metal Pb in groundwater by XRF spectrum was proposed to meet the rapid detection requirements ina wideconcentration range.The results showed that the optimum reaction environment for the enrichment of heavy metal Pb was pH7 and temperature 25o C.Under these conditions，the adsorption efficiency of Pb by Chlorella pyrenoidosa can reach more than 9O，and it has an excellent adsorption effect on Pb in the concentration range of 0.O127 9～0.3535mg/L ;based on the optimal reaction environment，the quantitative detection method of Pb was established by XRF spectroscopy. The average recovery rate of the method for the detection of actual groundwater samples was 98.74% ，which had excellent accuracy and stability. Therefore，it provides a scientific basis for the preventionandcontrolofheavy metal pollution in groundwater around theindustrial park.
