Abstract

A method of dissolving in an ionic liquid a metal in an initial oxidation state below its maximum oxidation state, characterised in that the ionic liquid reacts with the metal and oxidises it to a higher oxidation state. The initial metal may be in the form of a compound thereof and may be irradiated nuclear fuel comprising UO2 and/or PuO2 as well as fission products. The ionic liquid typically is nitrate-based, for example a pyridinium or substituted imidazolium nitrate, and contains a Bronsted or Franklin acid to increase the oxidising power of the nitrate. Suitable acids are HNO3, H2SO4 and [NO+]. Imidazolium nitrates and certain pyridinium nitrates form one aspect of the invention.

Description of the invention (3) The term " 金 蹰 " used in this article not only includes (〇) The gaseous state of the Gu element also includes an oxidation state of greater than zero, which is connected to other elements, such as ll (iv) and IMVI). Therefore, gold oxide in its original oxidation state may include metal compounds such as gold oxide. Gold plutonium preferably includes uranium (typically 1102 and / or Ua08) or plutonium (typically Pu02), or plutonium, and is usually a split product. 1102 or is not directly dissolved in the oxidizing ionic liquid, but the oxide and the ionic liquid are back ground to form an oxide species dissolved in the ionic liquid. The preferred dissolution method can be used for reprocessing of radiation nuclear fuel. The present invention also includes the use of oxidizing ionic liquids to dissolve other gold hafnium species, such as zirconium alloys, which can be in the form of a coating on a nuclear fuel rod. In another aspect, the present invention therefore provides a method for dissolving gold tincture in a «sub-liquid> below its maximum oxidation state, in which a о component of the ionic liquid is an oxidizing agent and oxidizes the gold tincture to a higher oxidation state. Gold tincture is typically its oxide form. The present invention further provides an ionic liquid, including a medicament for increasing the oxidizing power of the liquid, for example, to make a non-oxidizing liquid hip oxidizing. Therefore, the liquid will contain not only anions and cations, but also another component that enhances the ability of the tired body to oxidize the substrate. In a preferred embodiment, the liquid contains a moderately oxidizing anion [1003] and an acid that may be Bronsted or Franklin-rich acid such as UNO3, H2SO4 or [ N0 +], like [H0] [BP4]. Acid makes the liquid more oxidatively reactive to various substrates U0 2 and PuO 2.

The description of the invention (5) was reached. The present invention further includes the use of an ionic liquid to dissolve the fuel in the method for reprocessing the radiant fuel, K, and a reprocessing method which includes the step of dissolving the fuel in the ion liquid. Therefore, the present invention is limited to the use of broilers as a solvent, and the visual box is used as the reaction medium for the first time. Solvent solvents include ionic liquids, which usually contain a medicament or species that enables the solvent to oxidize the selected substrate, although this medicament is not necessarily present in the overall perspective of the present invention (see the following title "Golden Clam" Explained below). The agent may be an oxidizing agent dissolved in a non-oxidizing liquid or an auxiliary agent for increasing the oxidation reactivity of another oxide species. If the solvent contains nitrate ions, the increase in the oxidation reactivity of the solvent is beyond that provided by the nitrate ion itself; as mentioned above, the elixir includes Bronsted and Franklin acids. The solvent includes in principle any ionic liquid. But this liquid usually contains nitrate anions. The cation practice will include one or more organic cations, especially nitrogen heterocycles containing a quaternary nitrogen and more particularly N-substituted pyridinium or N, H'-disubstituted tritium files. The substituent is preferably a hydrogen carbon group and more preferably an alkyl group, which may be branched. Hydrocarbon groups (such as alkyl groups) typically contain 1 to 18 carbon atoms and some typically have 1 to 8 carbon atoms. The cation can therefore be a disubstituted sulfonium ion, where the substituent is in the form of CnH2n + 1, and the substituent is linear or branched. -.7- (Please read the precautions on the back before filling in this page) The Chinese standard for quick use of this paper standard (CNS > Λ4 specifications (2IOX2W public address) > 420809 A7 B7 Office of Central Standards Bureau, Ministry of Economic Affairs Printed by the cooperative V.

A 1-hexyl-3-methylphosphonium nitrate was prepared by a similar method, and this substance was liquid at room temperature. Other possible cations for gadolinium and gadolinium include quaternary phosphonium cations, such as tetrakis (gas-carbon based) gadolinium. The thin S carbon-based system is entangled with pyridium and radon cations as described above. Agents used to increase the oxidizing power of ionic liquids (when used, see > subtitle " metals ") are typically Bronsted acids (e.g. HH〇3 or Η 2 S0 4) or Franklin acids, such as [N0 + ], In any of the examples for making osmium nitrate more oxidatively reactive to substrates such as UO2 and Pu02. In other words, an ionic liquid of the present invention includes an oxidant containing nitrate and an accelerator thereof. The oxidant and the ionic liquid When combined, it can react with vitamin solution to produce a new species, which is also an ionic liquid. Therefore, it is believed that [N0] [BF4] reacts with the nitrate of organic cations to form the cation tetrafluoroammonium salt U).

At one point, the metallurgical system is relatively low in oxidation state before dissolution, and the ionic liquid system is oxidized. Preferably, the metallurgical system is in a state before dissolution in the ionic liquid. The solubility is lower than those in higher oxidation states, and the ionic liquid composition is oxidized. Gold dysprosium is typically in the form of oxides. Preferred gold dysprosium oxides include various uranium oxides and plutonium (IV) oxides. Therefore, to give just one example, 1] 〇2 can react with the broodstock liquid, which ionic liquid oxidizes uranium (W) compounds to (VI) species, such as oxidizing uranium dioxide to complexed form of trans-dioxonium uranium (VI). Similarly, plutonium (IV), usually PuO2, can be reacted with dimensional oxygen, the ionic liquid Plutonium (IV) is oxidized to plutonium (VI), for example, plutonium dioxide is oxidized to a complexed form of trans-dioxonium plutonium (VI).
