摘要
摘要 研究了用 Fe4[Fe(CN)6]3 从硝酸和盐酸溶液中回收 Rh、Ru 和 Pd 的可能性。确定了在 1-5 M 的酸浓度范围内从硝酸溶液中几乎完全回收铂族金属总和的条件。在酸浓度为 0.1-0.5 М 的盐酸溶液中，可以回收 Rh 和 Ru。钯可从 1-5 M 硝酸和 1-5 M 盐酸溶液中完全回收。在模拟的乏核燃料后处理溶液中，Cs、Mo 和 Zr 与 Rh、Ru 和 Pd 一起在不同程度上被回收。Rh 和 Ru 的吸附等温线由 Langmuir 方程描述。钯的吸附等温线具有非标准的两级形状。建议使用 Fe4[Fe(CN)6]3 从工艺溶液中回收铂金属，包括从乏核燃料和乏催化剂的后处理溶液中回收铂金属。
Recovery of Rhodium, Ruthenium, and Palladium from Nitric and Hydrochloric Acid Solutions with Iron(III) Hexacyanoferrate(II)
The possibility of recovering Rh, Ru, and Pd from nitric and hydrochloric acid solutions with Fe4[Fe(CN)6]3 was examined. The conditions for practically complete recovery of the sum of platinum group metals from nitric acid solutions at the acid concentrations in the interval 1–5 M were determined. From hydrochloric acid solutions, Rh and Ru can be recovered at the acid concentration of 0.1–0.5 М. Pd is completely recovered from both 1–5 M nitric and 1–5 M hydrochloric acid solutions. From simulated spent nuclear fuel reprocessing solutions, Cs, Mo, and Zr are recovered to different extents jointly with Rh, Ru, and Pd. The Rh and Ru sorption isotherms are described by the Langmuir equation. The Pd sorption isotherm has a nonstandard two-step shape. Fe4[Fe(CN)6]3 can be recommended for recovering platinum metals from process solutions, including those from reprocessing of spent nuclear fuel and spent catalysts.
期刊介绍：
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
