A rare metal extractant

Abstract

The present invention relates to provide a kind of extraction agent of rare metal, described extraction agent comprises lauryl alcohol ester, activity accelerator, triethylamine, hexylamine, phenylnaphthylamine and water; Wherein, with respect to 1 weight part The lauryl alcohol ester, the content of the active accelerator is 0.3-2.0 parts by weight, the consumption of the triethylamine is 0.3-3.0 parts by weight, the consumption of the hexylamine is 0.15-2.5 parts by weight, The consumption of the phenylnaphthylamine is 0.5-1.0 parts by weight, and the consumption of water is 20-50 parts by weight. The rare metal extracting agent of the invention can reduce procedures, promote recycling, has the advantages of wide application range, low cost of raw materials, and the like.

Description

technical field [0001] The invention relates to a metal extractant, in particular to a rare metal extractant. Background technique [0002] Rare metals are indispensable in our daily lives and are used in many modern precision instruments such as catalysts for automobiles, fuel cells, and super-strong magnets. However, in Japan, most of these metals are dependent on imports, and the recycling of rare metals is an important technology from the viewpoint of stable supply of resources and environmental protection. It is obtained by making an aqueous solution from a variety of wastes. The concentration, type and impurities of metals contained in the aqueous solution containing rare metals are also varied. Existing various extraction agents are subjected to multi-stage extraction and separation, which leads to time-consuming and cost. Therefore, providing extractants for rare metals has become an urgent problem to be solved by those skilled in the art. Contents of the inventi...
