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 ...
Evaluation of two ion-exchange membranes for the transport of tin in the presence of hydrochloric acid

García Gabaldón, Montserrat; Pérez-Herranz, Valentín; Ortega Navarro, Emma María (Elsevier, 2011-01-19)

The transport properties of two ion-exchange membranes in the presence of tin, as Sn(II) and Sn(IV), were investigated by chronopotentiometry and current-voltage curves. Since tin forms positively or negatively charged ...
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 ...
