However, when a liquid sample is directly measured, a relatively high scattering background is caused, and the detection capability of the X-ray fluorescence analysis technology on the element content in the liquid sample is very limited, usually only the ppm level can be achieved, and the detection requirement of the ppb level low-content heavy metal elements in surface water cannot be met. Therefore, it is necessary to adopt a pre-enrichment method to convert the sample to be tested into a solid form and increase the concentration of the element to be tested therein. The pre-enrichment method of low-content heavy metal elements in surface water comprises a co-precipitation method, an electrodeposition method, a solid phase extraction method and the like, wherein membranes and ion resins are usually adopted as adsorption media in the solid phase extraction method, and the ion resins are most commonly used.
At present, after the pre-enrichment process of heavy metal elements in water by using ion resin is finished, the following three forms are generally adopted: (1) taking out the enriched powder, pressing into a specific shape, and then sending into an instrument for detection; (2) eluting the enriched ion powder, evaporating the eluent to a special measuring paper disc, and then putting the paper disc into an instrument for detection; (3) the solution containing the ionic resin after enrichment was filtered onto filter paper and covered with a Mylar film before being sent to the instrument for measurement. After the ion resin is adopted for pre-enrichment in the prior art, the ion powder after enrichment needs to be further processed to be sent into an instrument for measurement, and the ion resin pre-enrichment instrument has the defects of complex operation, time consumption and easy introduction of external pollution.
