A three-stage chemical cleaning of ion-exchange membranes used in the treatment by electrodialysis of wastewaters generated in brass electroplating industries

Santana Barros, Kayo; Martí Calatayud, Manuel César; Pérez-Herranz, Valentín; Espinosa, Denise Crocce Romano (Elsevier, 2020-10-15)

[EN] After long-term electrodialysis, cleaning the membranes is crucial to extend their lifetime. In this work, we evaluate the effects of a three-stage chemical cleaning on electrochemical and structural properties of ...
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 ...
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 ...
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 ...
