Abstract

The invention relates to an ultrasonic preparation method and application of vanadium-extracting solvent-impregnated resin, and its technical scheme is: pretreatment is carried out by mixing and soaking a certain volume of macroporous adsorption resin and absolute ethanol; pretreated macroporous adsorption resin and Organic extraction solvents are mixed, and ultrasonically impregnated, then washed and filtered with deionized water, and vacuum-dried to obtain a vanadium extraction solvent impregnated resin prepared by ultrasonic impregnation, and the vanadium extraction solvent impregnated resin prepared by ultrasonic impregnation is used for vanadium-containing Separation and enrichment of solutions. Compared with the vanadium extraction solvent impregnated resin prepared by the constant temperature oscillation method, the preparation method of the present invention greatly shortens the impregnated equilibrium time on the basis of maintaining a relatively high equilibrium impregnation rate, improves the adsorption amount of vanadium by the solvent impregnated resin, and has the advantages of simple operation, Low energy consumption, high efficiency and other characteristics.

Description

technical field [0001] The invention belongs to the field of separation and enrichment of rare metals, and in particular relates to a solvent-impregnated resin for vanadium extraction and its preparation method and application. Background technique [0002] Vanadium is an important strategic resource, widely used in metallurgy, national defense, aviation, chemical industry and other fields. Stone coal is a kind of vanadium-containing resource unique to my country, and its reserves are very rich (Bao Shenxu et al., Global Vanadium Production, Consumption and Market Analysis [J]. China Mining. 2009, 18:12-15.). To extract vanadium from vanadium resources, vanadium needs to be leached from raw materials. During the leaching process, a large number of impurity ions will be leached together with vanadium. Therefore, the obtained vanadium-containing liquid needs to be separated and enriched. At present, the separation and enrichment technologies of vanadium-containing liquid main...
