WebRECOVERY OF URANIUM FROM BERYLLIUM-CONTAINING SOLUTIONS 521 RADIOCHEMISTRY Vol. 56 No. 5 2014 for binding F– ions and without it. The comparison results are given in Table 1. Table 1. Comparison of the static exchange capacities of the sorbentsa Sorbent Without Al(NO3)3 With Al(NO3)3 CU, mg L –1 –1S, mg g–1 C Be, mg … WebValues ranged from <0.05 to165 µg/L. Only four values exceeded 30 µg/L; these were all for raw water samples (New Brunswick Department of Health, 2015). Nine years of data from Quebec had an average uranium concentration of 6.7 µg/L. Of the 28,214 samples tested, 3294 were above the detection limit of 1 µg/L.
Uranium (VI) Recovery from Black Shale Leaching Solutions Using Ion …
Web20 dec. 2024 · In acidic leaching, uranium oxidation requires the presence of ferric ion, regardless of used oxidizing agents [ 10 ]. The oxidizing agent oxidizes ferrous ion to ferric ion that is oxidant for the uranium as shown in Eqs. 1, 2 and 3. UO 2 s + 2 Fe 3 + ⇄ UO 2 aq 2 + + 2 Fe 2 + E1 2 Fe 2 + + MnO 2 + 4 H + ⇄ 2 Fe 3 + + Mn 2 + + 2 H 2 O E2 WebConcentration of uranium: 7.14 × 10 −4 mol l −1 UO 2 (NO 3) 2.

WebBatch and field column tests showed that strong-base anion-exchange resins were more effective in removing uranium from both near-neutral-pH (6.5)- and high-pH (8)-low-nitrate-containing groundwaters, than metal-chelating resins, which removed more uranium from acidic-pH (5)-high-nitrate-containing groundwater from the Oak Ridge Reservation … Webconcentration of uranium 235 in mixtures with uranium 238 using ion exchange resins专利检索，concentration of uranium 235 in mixtures with uranium 238 using ion exchange resins属于··通过离子交换专利检索，找专利汇即可免费查询专利，··通过离子交换专利汇是一家知识产权数据服务商，提供专利分析，专利查询，专利检索等数据服务 ... WebUranium is widespread in nature and has been identified in many different minerals. It exists in several chemical oxidation states as well as a mixture of 3 radioisotopes. All naturally occurring isotopes of uranium are considered weakly radioactive, however, the principal health effects associated with uranium are due to its chemical toxicity. iope air cushion in shimmer beige
