Method for extracting uranium by using wind power generation-seawater uranium extraction coupling device

Abstract

The invention discloses a method for extracting uranium by using a wind power generation-seawater uranium extraction coupling device. The method comprises steps that In2O3-x is added into absolute ethyl alcohol, stirring and ultrasonic treatment are conducted, and absolute ethyl alcohol solution of In2O3-x is obtained; uniform smearing of the absolute ethyl alcohol solution of In2O3-x on carbon cloth is performed, and drying is performed to obtain In2O3-x carbon cloth with oxygen vacancy; the In2O3-x carbon cloth with oxygen vacancy is taken as a working electrode, and another blank carbon cloth is taken as a counter electrode; the working electrode and the counter electrode are respectively inserted into a plastic carrier plate of a coupling device; a small wind power generation device isfixed above a plastic carrier plate of the coupling device, and the working electrode and the counter electrode are connected with a storage battery of the small wind power generation device throughwires; the coupling device is placed in seawater, the storage battery is charged by the small wind power generation device in the presence of wind, and the working electrode and the counter electrodeare powered on through the storage battery, so the uranium is extracted from the seawater. The method is simple and feasible, and can be applied to uranium extraction operation of large-area seawater.

Description

technical field [0001] The invention relates to a method for extracting uranium from seawater, in particular to a method for extracting uranium by using a coupling device of wind power generation and seawater extracting uranium. Background technique [0002] Uranium is a raw material for nuclear power, and there are very few uranium reserves in natural ores. The ocean is a huge storehouse of uranium. The content of uranium in seawater is as high as 4.29 billion tons, which is thousands of times that of uranium on land. In addition, the uranium isotopes in seawater are mainly uranium-238 and uranium-235, which are the same as the natural abundance in terrestrial uranium deposits. If the uranium resources in the seawater can be effectively enriched, it will become an important supplement and guarantee for the stable supply of fuel for the nuclear power industry. [0003] Currently, uranium extraction methods mainly include chemical precipitation, ion exchange, membrane separ...

Problems solved by technology

The chemical precipitation method has simple equipment, low cost and high efficiency, but the polymer produced by the reaction needs to be further concentrated, dehydrated and solidified; the ion exchange method has high extraction efficiency and good purification effect, but is expensive, poor in selectivity, and limited in exchange capacity; The separation method is simple to operate, low in energy consumption, and strong in adaptability, but it has high requirements on the quality of raw water and often needs to be used in combination with other water treatment technologies; while the adsorption method requires a large amount of treatment and strong selectivity of the adsorbent for the adsorbent. , strong corrosion resistance, high mechanical strength, etc., and the existing adsorption materials still have defects such as low adsorption efficiency, high production cost, and difficult recycling and reuse in practical applications.
