Determination of transport properties of Ni(II) through a Nafion cation-exchange membrane in chromic acid solutions

Martí Calatayud, Manuel César; García Gabaldón, Montserrat; Pérez-Herranz, Valentín; Ortega Navarro, Emma María (Elsevier, 2011-07-07)

The transport properties of a cation-exchange membrane in the presence of nickel sulphate solutions were investigated by means of chronopotentiometry. The interest of this study relies on the application to the treatment ...
Effect of the equilibria of multivalent metal sulfates on the transport through cation-exchange membranes at different current regimes

Martí Calatayud, Manuel César; García Gabaldón, Montserrat; Pérez-Herranz, Valentín (Elsevier, 2013-09-15)

The transport of trivalent metals (Cr(III) and Fe(III)) through cation-exchange membranes is studied and compared with the transport of mono- and divalent ions by means of chronopotentiometry and current-voltage characteristics. ...
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 ...
Study of the effects of the applied current regime and the concentration of chromic acid on the transport of Ni2+ ions through Nafion 117 membranes

Martí Calatayud, Manuel César; García Gabaldón, Montserrat; Pérez-Herranz, Valentín (Elsevier, 2012-12-23)

In the present work galvanostatic experiments are conducted with an electrodialysis cell in order to study the passage of Ni 2+ ions present in chromic acid solutions through a Nafion cation-exchange membrane. The competing ...
STUDY OF THE TRANSPORT OF HEAVY METAL IONS THROUGH CATION-EXCHANGE MEMBRANES APPLIED TO THE TREATMENT OF INDUSTRIAL EFFLUENTS

Martí Calatayud, Manuel César (Universitat Politècnica de València, 2015-01-12)

La presente Tesis Doctoral consiste en la determinación de las propiedades de transporte de diferentes especies catiónicas a través de membranas de intercambio catiónico. Las membranas de intercambio iónico son un componente ...
Sulfuric acid recovery from acid mine drainage by means of electrodialysis

Martí Calatayud, Manuel César; CARDOSO BUZZI, DANIELLA; García Gabaldón, Montserrat; Ortega Navarro, Emma María; Bernardes, A.M.; Suarez Tenorio, Jose Alberto; Pérez Herranz, Valentín (Elsevier, 2014-06-16)

In the present work the recovery of sulfuric acid from acid mine drainage by means of 3-compartment electrodialysis (ED) is evaluated. An effective recovery of sulfuric acid free from Fe(III) species was obtained in the ...
