Problems solved by technology

[0005] The methods for purifying vanadium reported in the current literature have complex components, long process routes, and easy introduction of new impurities. Therefore, it is necessary to invent a new type of adsorption material to directly extract vanadium from the solution to improve the adsorption capacity of vanadium.

Abstract

The invention relates to a preparation method of a purified vanadium adsorption material. Bis(cyclopentadiene) vanadium iodide and octadecendioic acid are introduced in the polymerization process; 1-allyl-3-buthylimidazole tetrafluoroborate is used for polymerization and preparation.

Description

technical field [0001] The invention relates to the preparation of an adsorbent, in particular to the preparation of a purified vanadium adsorption material. Background technique [0002] In the process of leaching and extracting vanadium from vanadium-containing clinker, some impurities are also leached into the solution together with vanadium. The vanadium-containing leach solution usually contains impurity ions such as iron, manganese, chromium, silicon, phosphorus, aluminum, calcium, etc., which affect the precipitation. The quality of vanadium and products, these impurity ions are under the adjustment of the pH value of the leaching solution, most of the impurity ions undergo hydrolysis reaction and precipitate into the sedimentation residue, but phosphorus, silicon, calcium and aluminum still form soluble compounds after hydrolysis and remain in the leaching solution , Seriously affect Shen vanadium and product quality, must be removed. Therefore, special purification...
