Chronopotentiometric study on the simultaneous transport of EDTA ionic species and hydroxyl ions through an anion-exchange membrane for electrodialysis applications

Santana Barros, Kayo; Martí Calatayud, Manuel César; Ortega Navarro, Emma María; Pérez-Herranz, Valentín; Espinosa, Denise Crocce Romano (Elsevier, 2020-12-15)

[EN] The use of EDTA as a complexing agent in electrodialysis has gained increasing attention in several industrial applications. Variations in pH at the membrane surface are known to alter the chemical equilibrium of EDTA ...
Electrodialysis for concentrating cobalt, chromium, manganese, and magnesium from a synthetic solution based on a nickel laterite processing route

Feijoo, G. C.; Santana-Barros, Kayo; Scarazzato, T.; Espinosa, D.C.R. (Elsevier, 2021)

[EN] Due to environmental and human health concerns, the need for cleaner techniques able to extract and recover metals from mining process solutions has been increasing. In this work, the use of electrodialysis for ...
Evaluation by Means of Electrochemical Impedance Spectroscopy of the Transport of Phosphate Ions through a Heterogeneous Anion-Exchange Membrane at Different pH and Electrolyte Concentration

Rotta, Eduardo Henrique; Martí Calatayud, Manuel César; Pérez-Herranz, Valentín; Moura Bernardes, Andréa (MDPI AG, 2023-01)

[EN] Electrodialysis is an innovative technique to reclaim phosphates from municipal wastewater. However, chemical reactions accompany the transport of these ions through ion-exchange membranes. The present study investigates ...
Treatment of Cyanide-Free Wastewater from Brass Electrodeposition with EDTA by Electrodialysis: Evaluation of Underlimiting and Overlimiting Operations

Santana Barros, Kayo; Scarazzato, Tatiana; Pérez-Herranz, Valentín; Espinosa, Denise Crocce Romano (MDPI AG, 2020-04)

[EN] Growing environmental concerns have led to the development of cleaner processes, such as the substitution of cyanide in electroplating industries and changes in the treatment of wastewaters. Hence, we evaluated the ...
