Recent advances of rhenium separation and enrichment in China
The rhenium could also be stripped by sulfuric acid solution (4 mol/L). In 2010, Jiang et al. prepared a novel trialkyl amine (N235) extractive resin and studied its extraction behavior of rhenium and molybdenum [44]. The influencing factors such as extraction time, concentrations of Re and Mo, pH of the extraction medium were investigated.
