Abstract

The invention discloses an enrichment device for trace multivalent cations. The enrichment device comprises a micron-grade main channel, wherein a first inlet which is used for connecting to-be-enriched stoste containing multivalent cations is formed in the micron-grade main channel; a first buffer pool is connected to the outlet end of the micron-grade main channel; a first anion exchange membrane is arranged on the inner wall of the micron-grade main channel; the outer end of the first anion exchange membrane is communicated with a second buffer pool; an area, corresponding to the first anion exchange membrane, of the micron-grade main channel, is a separation area; an upstream, relative to the first anion exchange membrane, of the micron-grade main channel, is a trace ion enriching area; a second inlet is also formed in the trace ion enriching area; a control valve for opening and closing the second inlet is arranged at the second inlet. The enrichment device disclosed by the invention has the advantage of low cost; in addition, the trace multivalent metal ions (such as Mg<2+>, Cu<2+>, Ca <2+> and Fe <3+>) in a water body can be efficiently enriched.

Description

technical field [0001] The invention belongs to the technical field of metal element detection, and in particular relates to a device for enriching trace polyvalent metal ions. Background technique [0002] In recent years, metal pollution has become a prominent environmental problem. Collective metal poisoning incidents have been reported continuously all over the country, even threatening the survival of human beings. Especially in water bodies, the natural background content of polyvalent metals does not have obvious harm, but with the increase of social population and the acceleration of industrialization, a large amount of industrial wastewater and domestic sewage are discharged, especially soluble polyvalent metals enter the water body and pass through Drinking water, bioaccumulation, and food chains have a series of toxic effects on organisms in water bodies, and ultimately endanger human health. There are many kinds of polyvalent metal ions in water, and most of the...
