Description
Technical field
The present invention relates to uranium-containing waste water, extraction of uranium from seawater fields, and in particular to the metal organic frame synthesis based on amidoxime
MIL-53(Al)-AO2Preparation method.
Background technology
With the fast development of nuclear industry, the peaceful use of nuclear energy generates a large amount of radwastes, wherein containing difference
The radionuclide of type.In addition, in nuclear fuel production and process, inevitably some uranium is released to certainly
In right environment.The problem of pollution of the uranium (VI) disperseed in Uranium tailings is World Focusing.Free uranium (VI) ion can pass through
Food chain accumulates, and eventually enters into human recycle system.Radioactive uranium (VI) ion can purchase the biological tissue for destroying human body.In order to
The stabilization of public health and the ecosystem is removed the radionuclide in waste water, is released into most important in natural environment.
From the point of view of safe and healthy angle, there is uranium chemical toxicity and radiotoxicity, uranium-containing waste water to have the uranium of suitable concentration
Human body can be damaged, so Scientific Engineering worker constantly explores new method to enable uranium-containing waste water recycling,
Prevent it from being damaged to environment.From the point of view of energy security angle, uranium is the basic energy resource of nuclear industry development, it is ensured that energy security
The discharge of greenhouse gases can be reduced simultaneously.The adsorbent of synthesizing new stability and high efficiency is studied, it is water-soluble by the way that adsorbent to be placed in
With the uranium in adsorption aqueous solution in liquid, adsorption capacity, stability, absorption mechanism of adsorbent etc. are studied to extract uranium for seawater
Possible research direction is provided.
It is Cl, Na, Mg, S, Ca, Br, C, Sr, B that the main component of element is dissolved in seawater, and ratio is more than 99.9%.Trace
The uranium ion of amount exists in seawater.According to the average salt content (about 3.5%) in seawater, total salt concentration is uranium content
106–107Times.Oxidation state of the uranium with long half-lift, complicated Coordinative Chemistry and several stabilizations in aqueous medium.Uranium is in sea
Main solubilised state in water is hexavalent uranium (U6+) uranyl tricarbonate complex [UO2(CO3)3]4–.Dissolved uranium species in seawater
Form is mainly by CO2The influence of concentration and pH.Therefore, HCO present in seawater3 –/CO3 2–Buffer advantageously forms thricarbonate
Uranyl complex [UO2(CO3)3]4–.This complex compound is stable in pH ≈ 8, and is easy to divide respectively in the range of pH 6-8 and 5-7
Solution is [UO2(CO3)2]2–[UO2(CO3)] complex compound.(contain in every cubic metre of seawater although the concentration of URANIUM IN SEAWATER is only 3ppb
~3 milligrams of uranium), contain about 4,500,000,000 tons of uranium in the enormousness of all oceans (about 13.7 hundred million cubes of kms).If this
Resource has 50% can recycle, and will be sufficient to maintain global nuclear reactor and operates about 6500.In a variety of actinides, uranium is core
The main and common fuels of reactor.Therefore, people have prodigious interest to extract uranium from seawater, and use it as one kind and replace
The sustainable energy in generation.
Conventional method mainly have chemical precipitation, ion exchange, evaporation and concentration, extraction, UF membrane, electrochemistry, sedimentation crystallization,
Condensation flocculation and absorption method.Absorption method has the characteristics that applied widely, efficient and bioaccumulation efficiency is high, is highly suitable for containing
The separation of uranium Uranium in Waste Water and the enrichment of URANIUM IN SEAWATER.But since the selective adsorption capacity of current adsorbent mostly is relatively low,
It is unfavorable for the extraction recycling of Uranium in Waste Water.
Oximido and amino are contained simultaneously in amidoxime functional group, and lone pair electrons and the uranyl ion of non-bonding occur coordination and make
With formation chelate.Since amidoxime group has very strong chelation to uranium, modification inorganic nano material can be applied to
And high molecular polymer, to improve adsorption capacity of the adsorbent to uranium.Due to the specific surface area of metal organic frame itself, hole body
Product, tenor has considerable degree of advantage performance and metal organic frame to be synthesized with simple experiment condition
It is accordingly modified according to experiment purpose after the completion.Meanwhile amidoxime group compound has to the very strong complexing power of uranium, acyl
Amidoxime base functional group provides new breakthrough in terms of metal organic frame improves adsorbent to the adsorption capacity of uranium.
