Ion exchange in complexing media – Nickel removal from ammoniacal ammonium sulfate solutions
In real hydrometallurgical systems, ion exchange of metal cations is often accompanied by competing processes, such as complex formation. In this paper, we have analyzed influence of complex formation on nickel uptake in ...
Ion exchange recovery of rhenium from industrially relevant sulfate solutions: single column separations and modeling
In this study, phenomena behind recovery of Re by weak anion exchangers from sulfate solutions containing Mo and As as impurities were investigated. All the metals exist as different kinds of oxyanions or, at some conditions, ...
Recovery of metal oxoanions from basic solutions using cooperative sorption – Separation of Na2MoO4 and NaOH
Chromatographic separation of molybdate oxoanions and NaOH was studied using cooperative sorption as a method to recover both Mo and the base as concentrated solutions. Commercial non-ionic microporous adsorbents composed ...
