Electrowinning of iron from spent leaching solutions using novel anion exchange membranes

Badenhorst, Wouter Dirk; Rossouw, Cloete; Kerres, Jochen; Bruinsma, Dolf; Krieg, Henning (MDPI, 2019)

In the Pyror process, electrowinning (EW) is used to recover acid and iron from spent leaching solutions (SLS), where a porous Terylene membrane acts as a separator between the cathode and anode. In this study, a novel ...
Novel anion exchange membrane based on poly(pentafluorostyrene) substituted with mercaptotetrazole pendant groups and its blend with polybenzimidazole for vanadium redox flow battery applications

Cho, Hyeongrae; Krieg, Henning M.; Kerres, Jochen A.; Atanasov, Vladimir (Elsevier, 2020)

In order to evaluate the performance of the anion exchange membranes in a vanadium redox flow battery, a novel anion exchange polymer was synthesized via a three step process. Firstly, 1-(2-dimethylaminoethyl)-5-mercaptotetrazole ...
