“…A number of methods including ion exchange, adsorption, solvent extraction and precipitation have been adopted to raise rhenium output. [6][7][8][9] Compared to other techniques, the ion exchange method has been widely used in the recovery of rhenium due to its advantages such as convenient operation and environmental friendliness. Rhenium is a redox-insensitive nuclide and its oxidation states are mainly presented as a stable state of perrhenate anion (ReO 4 À ) in a wide pH range and it also has a relatively strong affinity with functionalized resins.…”

A new organic synthetic anion exchange resin (LSC-436) containing cyclohexylamine group was prepared for the sorption of rhenium. The traditional batch tests were applied to investigate the mechanism of sorption for rhenium on LSC-436 with respect to contact time, initial rhenium concentration, the value of pH and the amount of resin. The experimental data obtained from batch tests were modeled using the Langmuir/Freundlich isotherms and pseudofirst-kinetic and pseudo-second-kinetic models to obtain key dynamic parameters for investigating the mechanism of sorption of rhenium. The LSC-436 resin was characterized using scanning electron microscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) techniques to further study the sorption mechanism.

BACKGROUND: Rhenium is a rare and valuable metal coexisting with molybdenum in molybdenite and sulfide copper ores and is hard to separate. Methods such as solvent extraction, ion exchange, adsorption, precipitation, etc. have been used to separate and purify Re(VII), and resin ion exchange has been widely investigated and used owing to its convenient operation and relatively low-cost. The main challenge comes from the preparation of resins having high performance and stability. In an earlier study, an N-methylimidazolium functionalized strong basic anion exchange resin was successfully synthesized and used for Cr(IV) extraction. This paper, reports on further synthesis and application of this resin for adsorption and separation of Re(VII) and Mo(VI), especially from copper arsenic filter cake. RESULTS: At pH 6.25, Re(VII) and Mo(VI) can be effectively separated with the N-methylimidazolium functionalized strong basic anion exchange resin, giving a Re(VII) recovery of up to 93.3%, but only 5.1% for Mo(VI). When using the copper arsenic filter cake sample 89.1% Re(VII) recovery was achieved. CONCLUSION: The N-methylimidazolium functionalized strong basic anion exchange resin exhibited high selectivity and recovery for Re(VII) in a mixed system.
