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...
