Characterization of an anion-exchange membrane subjected to phosphate and sulfate separation by electrodialysis at overlimiting current density condition

Rotta, Eduardo Henrique; Marder, Luciano; Pérez-Herranz, Valentín; Moura Bernardes, Andréa (Elsevier, 2021-10-01)

[EN] The structural degradation of an anion-exchange membrane used on the separation of phosphate from sulfate ions at overlimiting current density conditions was investigated. To this, the chemical structure changes, ...
Electrodialysis for the tertiary treatment of municipal wastewater: Efficiency of ion removal and ageing of ion exchange membranes

Rodrigues Gally, Caline; Benvenuti, Tatiane; da Trinidade, Carolina de Moraes; Siqueira Rodrigues, Marco Antonio; Zoppas Ferreira, Jane; Pérez-Herranz, Valentín; Moura Bernardes, Andréa (Elsevier, 2018-10)

[EN] Electrodialysis was applied as a tertiary treatment for effluents from a Brazilian sewage treatment plant, and the results are discussed in terms of membrane ageing and process efficiency. Current-voltage analysis and ...
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 ...
Investigation of ion-exchange membranes by means of chronopotentiometry: A comprehensive review on this highly informative and multipurpose technique

Santana Barros, Kayo; Martí Calatayud, Manuel César; Scarazzato, Tatiana; Moura Bernardes, Andréa; Espinosa, Denise Crocce Romano; Pérez-Herranz, Valentín (Elsevier, 2021-07)

[EN] Electrodialysis is mostly used for drinking water production but it has gained applicability in different new fields in recent decades. Membrane characteristics and ion transport properties strongly influence the ...
Using p-Si/BDD anode for the electrochemical oxidation of norfloxacin

Wohlmuth da Silva, Salatiel; Ortega Navarro, Emma María; Siqueira Rodrigues, Marco A.; Moura Bernardes, Andréa; Pérez-Herranz, Valentín (Elsevier, 2019-01-01)

[EN] This study evaluated the electrochemical advanced oxidation process (EAOP) using boron-doped diamond (p-Si/BDD) anode in the abatement of the antibiotic norfloxacin (NOR). The influence of the applied current density ...
