Abstract

The invention relates to the technical field of separation devices and provides a metal ion separation device. The metal ion separation device comprises an adsorption tower and a desorption tower, wherein an upper liquid distributor of the adsorption tower and a lower liquid distributor of the adsorption tower are fixedly installed in an upper inner cavity and a lower inner cavity of the adsorption tower respectively; an upper liquid distributor of the desorption tower and a lower liquid distributor of the desorption tower are fixedly installed in an upper inner cavity and a lower inner cavity of the desorption tower respectively; strongly acidic cationic resins are fixedly installed in an adsorption tower inner cavity between the upper liquid distributor of the adsorption tower and the lower liquid distributor of the adsorption tower; strongly acidic cationic resins are fixedly installed in a desorption tower inner cavity between the upper liquid distributor of the desorption tower and the lower liquid distributor of the desorption tower. The metal ion separation device has a reasonable and compact structure, is convenient to use, has the characteristics of strong selectivity, big concentration multiple, high enrichment efficiency, high enrichment speed, low investment, low operating cost, simplicity in procedure operation and control and the like and is especially suitable for separation and enrichment of the metal ions in low-concentration solutions.

Description

technical field [0001] The invention relates to the technical field of separation devices, and relates to a metal ion separation device. Background technique [0002] With the rapid development of the global economy, heavy metal pollution has become a global environmental pollution problem, seriously affecting human health and even life. Heavy metal pollution is different from pollution from other organic compounds. Many organic compounds can reduce or eliminate their harmfulness through physical, chemical or biological purification of nature itself. However, heavy metals are difficult to degrade in the environment, easy to be enriched by organisms, and have the characteristics of biomagnification and high toxicity. At present, due to the mining, smelting, processing and chemical wastewater discharge of heavy metals in our country, many heavy metals such as lead, mercury, cadmium, cobalt, etc. enter the atmosphere, water, and soil, causing serious environmental pollution. ...
