摘要
The ultrafiltration concentration of rhenium is investigated with the use of the Praestol flocculants of the cation type using a setup with separating membranes in the form of polysulfone-based hollow fibers. The dependence of selectivity of the membrane on the impurity concentration in the solution is studied. The possibility of eluting rhenium from the obtained concentrates is shown. When extracting rhenium from mineralized solutions that model the composition of natural chloride-sulfate waters, the selectivity of the membrane reaches 88% for three cycles of the complex-forming ultrafiltration.
