1. heavy metal detection method in water associated with a SPE and XFR, it is characterised in that bagInclude following steps:

  • (1) water sample to be detected is processed through pretreating device, filter out solid particle therein;

    (2) water sample to be measured after filtering is placed in solid phase extraction device so that it is in heavy metal element richCombine on the metal enrichment sheet in solid-phase extraction device;

    (3) the metal enrichment sheet XFR detector being enriched with heavy metal is detected, obtain describedThe fluorescence intensity level of heavy metal element in water sample to be measured;

    (4) take multiple different heavy metal, be configured to the titer of a series of variable concentrations respectively, and useHeavy metal therein is enriched with by metal enrichment sheet, then detects with XFR detector, draws notSame heavy metal, the fluorescence intensity level of variable concentrations, and draw the concentration of this heavy metal-glimmering according to concentrationLight intensity standard curve, every kind of corresponding calibration curve of element;

    (5) by the fluorescence intensity of the fluorescence intensity of step (3) gained Yu step (4) gained standard liquidCompare, draw kind and the concentration of heavy metal in described water sample to be measured.
