Document Type and Number:
WIPO Patent Application WO/2021/121213
Kind Code:
A1
Abstract:
Disclosed is a method for extracting uranium by means of a wind power generation-seawater uranium extraction coupling device, the method comprising: adding In2O3-x to absolute ethanol, and stirring and sonicating same, in order to obtain an anhydrous ethanol solution of In2O3-x; evenly applying the anhydrous ethanol solution of In2O3-x to a carbon cloth and drying same to obtain a carbon cloth of In2O3-x with oxygen vacancies; using the carbon cloth of In2O3-x with oxygen vacancies as a working electrode and using another blank carbon cloth as a counter electrode, and respectively inserting the working electrode and the counter electrode into a plastic carrier plate of the coupling device; fixing a small wind power generation device above the plastic carrier plate of the coupling device, connecting the working electrode and counter electrode with a storage battery of the small wind power generation device by means of wires; and placing the coupling device in sea water, wherein the storage battery is charged by the small wind power generation device in the presence of wind, and the working electrode and the counter electrode are powered on by means of the storage battery, so that the uranium is extracted from the seawater. The extraction method is simple and easy to implement, and can be applied to uranium extraction operations on large areas of seawater.
