摘要：In order to analyze the elution concentration of heavy metals eluted from

heavy metals contaminated with heavy metals, the analysis time can be shortened

compared with the official method without requiring high analytical instruments, and the

exact value according to the official method in the field The result of the diffraction is

obtained. The process of adjusting the solid liquid ratio for the contaminated soil to be

analyzed (S2) andThe process of elution of heavy metals by irradiating a contaminated

soil solution with a solid liquid ratio to microwave (S3)The process of extracting the

supernatant by centrifuging the eluent eluted by heavy metals (S4) andThe supernatant

is filtered to remove the eluent of heavy metals (S5) andThe process of forming a

chelating complex by adding a chelating agent to the eluent of the heavy metal

extracted and filtered (S6)X-ray fluorescence analysis of the generated chelate

complexesThe step (S7) for analyzing the eluting concentration of heavy metals is
