Uranyl species sorbed on cation exchanger from H2SO4 and HCl solution are thoroughly studied by IR spectra and equivalent accounting. The spectra are recorded with DIGILAB FTS-15C infrared spectrometer. The assymetric stretch, v3 of the uranyl group is infrared active. UO2 2+ and (UO2HSO4)+ from H2SO4 solution and UO2 2+ and (UO2Cl)+ from HC1 solution are found to be sorbed on the cation resin. The species sorbed on cation exchanger shows only a single band at 945.3cm-1. or 949.2cm-1 when the equilibrium is carried out in the solution with very low concentration of H2SO4 or HC1 respectively. The species should be UO2 2+. However, a new band at 902.9cm-1 or 906.6 cm-1 is found when the equilibrium is carried out in the solution with high concentration of H2SO4 or HC1 respectively. With increasing the acidity of the equilibrium solution the gradual increase of intensity of the new band and the gradual decrease of intensity of the original one can be observed. As a cation exchanger selectively sorbs cation, the species now sorbed should be either (UO2HSO4)+ or (UO2Cl)+. But the amount of (UO2HSO4)+ or (UO2Cl)+ on the cation exchanger can be ignored with a concentration of acids less than 0.5 N, The equivalent accounting method is applied to the resin loaded with uranyl ion and hydrogen ion, together with cation uranyl complex species, under the conditions of negligible invasion of uarnyl species. A known amount of resin in hydrogen form is equilibrated in a batch process with a solution containing uranyl and sulfuric acid(or hydrochloric acid) at various ratios. It is found experimentally that the amount of (UO2HSO4)+ or (UO2Cl)+ sorbed on exchanger is so low that they can not be observed by the method within experimental errors.It may be concluded that the (UO2HSO4)+ or (UO2 Cl)+ sorbed on cation exchanger can be overlooked under the general conditions of the experiment.

本文用红外光谱法和当量计算法研究了在硫酸、盐酸介质中铀(Ⅵ)在阳离子交换树脂上的化学状态及其含量。结果表明,在阳离子交换树脂上,铀(Ⅵ)除了以UO_2~(2+)外,还可以(UO_2HSO_4)~+和(UO_2Cl)~+存在,但当酸的浓度低于 0.5N时,其量可忽略不计。即使在酸浓度相当大(2—3N)时,(UO_2HSO_4)~+和(UO_2Cl)~+也只占树脂交换容量的很小一部分。因此,在通常用的阳离子交换色层法富集铀同位素的工作中,可以按照阳离子交换树脂上只有 UO_2~(2+)来考虑同位素效应及计算分离因数。

In this paper, uranyl species sorbed on anion exchanger from HC1 solution are throughly studied by equivalent accounting, determination of distribution ratio and IR spectra. The equivalent accounting method is applied under flow conditions for the anion exchange resin loaded solely with anion chloride species of uranyl by means of column chroma-tography, and also under batch conditions for resin loaded with anion chlaride species of uranyl as well as chloride ion. It is experimentally found that the charge...

In this paper, uranyl species sorbed on anion exchanger from HC1 solution are throughly studied by equivalent accounting, determination of distribution ratio and IR spectra. The equivalent accounting method is applied under flow conditions for the anion exchange resin loaded solely with anion chloride species of uranyl by means of column chroma-tography, and also under batch conditions for resin loaded with anion chlaride species of uranyl as well as chloride ion. It is experimentally found that the charge of the species is approximately equal to 2 and the ligand number of UO2 2+ is approximately equal to 4.The results of the determination of the sorption equilibra of uranyl show that the dependence of distribution ratio of uranyl on the concentrations of uranyl in anion resin supports the assumption that uranyl species sorbed on anion resin is (UO2Cl4)2-. The IR spectra are recorded with DIGILAB FTS-15C infrared spectrometer in the region from 4000 cm-1 down to 400 cm-1. The asymmetric stretch, v3 of the uranyl group is infrared active. The band at 914.3 or 918.1 cm-1 is assigned to the anion (UO2C14)2- sorbed on anion exchange resin from solutions of various concentrations of HC1.In conclusion, the predominant species sorbed on anion exchange resin is (UO2C14)2-from solutions of various concentrations of HC1.

用当量计算、分配比的测定以及红外光谱等三种实验方法,证明从盐酸介质中吸附到强碱性阴离子交换树脂上的铀酰,主要是以(UO_2Cl_4)~(2-)存在。
