Enhancing Palladium Recovery Rates in Industrial Residual Solutions through Electrodialysis
Zimmermann, Pauline; Tekinalp, Önder; Wilhelmsen, Øivind; Deng, Liyuan; Burheim, Odne Stokke (Peer reviewed; Journal article, 2023)Palladium is a vital commodity in the industry. To guarantee a stable supply in the future, it is imperative to adopt more effective recycling practices. In this proof-of-concept study, we explore the potential of ... -
Heat to Hydrogen by RED—Reviewing Membranes and Salts for the RED Heat Engine Concept
Zimmermann, Pauline; Solberg, Simon Birger Byremo; Tekinalp, Önder; Lamb, Jacob Joseph; Wilhelmsen, Øivind; Deng, Liyuan; Burheim, Odne Stokke (Peer reviewed; Journal article, 2022)The Reverse electrodialysis heat engine (REDHE) combines a reverse electrodialysis stack for power generation with a thermal regeneration unit to restore the concentration difference of the salt solutions. Current approaches ... -
Limiting current density as a selectivity factor in electrodialysis of multi-ionic mixtures
Zimmermann, Pauline; Tekinalp, Önder; Solberg, Simon Birger Byremo; Wilhelmsen, Øivind; Deng, Liyuan; Burheim, Odne Stokke (Peer reviewed; Journal article, 2023)Electrodialysis is a promising technology to remove low concentrations of target ions from multi-ionic mixtures. While the synthesis of selective membranes is a prominent topic in research, few studies have been presented ... -
Selective recovery of silver ions from copper-contaminated effluents using electrodialysis
Zimmermann, Pauline; Wahl, Kristin; Tekinalp, Önder; Solberg, Simon Birger Byremo; Deng, Liyuan; Wilhelmsen, Øivind; Burheim, Odne Stokke (Journal article; Peer reviewed, 2024)With the growing demand for silver, the recycling of this precious metal from secondary sources has become imperative. However, the presence of copper impurities poses a significant challenge. This study aims to explore ...
