Multicomponent absorption of anions in commercial anion-exchange membranes

Adsorption of F<sup>-</sup>, NO<sub>3</sub><sup>-</sup> and SO<sub>4</sub><sup>2-</sup> on AFN Anionic Membrane: Kinetics and Thermodynamics Studies

“…This result confirms that the ion exchange capacity is independent from the nature of the counter-ion [27].…”

On the structure–properties relationship of the AMV anion exchange membrane

“…It has been recognized that, although based on a chemically homogeneous polymer, any ion exchange membrane exhibits microheterogeneity [7][8][9][10][11][12]. There are several approaches allowing description of the transport properties of these systems, e.g., capillary models [8,9], and the microheterogeneous model [10,11].…”

“…There are several approaches allowing description of the transport properties of these systems, e.g., capillary models [8,9], and the microheterogeneous model [10,11]. In the former approach, the membrane is described as an ideal porous medium containing parallel and cylindrical pores of the same radius.…”

“…In the former approach, the membrane is described as an ideal porous medium containing parallel and cylindrical pores of the same radius. By applying the capillary models, the average radius of pores in the AMV membrane equilibrated in pure water was found to be 2.4 nm [9], but it is actually difficult to describe quantitatively a real ion exchange membrane as an array of cylindrical pores of identical radius. In the latter approach, the membrane is described as a microheterogeneous multiphase system with at least two phases (a gel phase and an interstitial solution [10,11]) and the transport modeling is based on a combination of the properties of each phase.…”

Physicochemical characterization of a polymeric conductor: application to defluoridation of industrial effluent by electrodialysis

“…The results shown in Table 1 confirm that ion-exchange capacity is independent of the nature of the counter-ion. 14…”
