摘要

水相两相萃取(APTE)是一种分离金属离子的环保型技术。研究人员使用由异癸醇聚氧乙烯醚(E-1006)、硫酸铵和水组成的新型水相两相体系(ATPS),对水溶液中 Re (VII) 和 Mo (VI) 的分离进行了研究。绘制了该体系的相图,并考察了 pH 值、温度、萃取时间、E-1006 和 (NH4)2SO4 的浓度以及金属离子对 Re (VII) 和 Mo (VI) 分离的影响。结果表明,在 pH 值为 7.0 时,Mo (VI) 几乎转化为富含 (NH4)2SO4 的相,而 Re (VI) 则被萃取到富含 E-1006 的相中。温度的升高导致 Mo (VI) 向富盐相转变,不利于萃取 Re (VII)。增加 E-1006 和 (NH4)2SO4 的浓度对铼和钼的分离有积极作用。总之,由 200 克/升 E-1006、200 克/升 (NH4)2SO4 和水组成的 ATPS 对 Re 的萃取效率高达 97.2%,对 Re (VII) 和 Mo (VI) 的萃取效率高达 2700,从 0.模拟浸出液的分离研究表明,Re (VI) 的萃取效率为 99.1%,Re (VII) 和 Mo (VI) 的分离系数为 5100。

Efficient Separation of Re (VII) and Mo (VI) by Extraction Using E-1006–Ammonium Sulfate Aqueous Two-Phase System
Aqueous two-phase extraction (APTE) stands out as an environmentally friendly technique for the separation of metal ions. The separation of Re (VII) and Mo (VI) in an aqueous solution was investigated using a novel aqueous two-phase system (ATPS) consisting of isodecanol polyoxyethylene ether (E-1006), ammonium sulfate, and water. A phase diagram of this system was developed, and the effects of pH, temperature, extraction time, the concentrations of E-1006 and (NH4)2SO4, and metal ions on the separation of Re (VII) and Mo (VI) were examined. The results show that at pH 7.0, Mo (VI) had almost transformed into the (NH4)2SO4-rich phase, while Re (VI) was extracted into the E-1006-rich phase. The increase in temperature induces a transition of Mo (VI) to the salt-rich phase, which is unfavorable for the extraction of Re (VII). The increase in the concentrations of E-1006 and (NH4)2SO4 has a positive effect on the separation of rhenium and molybdenum. Overall, the ATPS consisting of 200 g/L of E-1006, 200 g/L of (NH4)2SO4, and water yields an extraction efficiency of 97.2% for Re and a high separation factor of 2700 for Re (VII) and Mo (VI) from a mixture of 0.1 g/L of Re (VII) and 5 g/L of Mo (VI) at pH 7.0 and 323.15 K. Separation studies of the simulated leaching solution show that the extraction efficiency for Re (VI) is 99.1% and the separation factor of Re (VII) and Mo (VI) is 5100.
