Abstract

The transport of As (V) oxianions was modeled through the boundary layer generated between the bulk of an acidic As (V) electrolyte and the surface of an anionic exchange membrane during a batch electro dialysis process without agitation. The model was adapted from one developed for the transport of Cu (II) ions in the Nernst layer under the same hydrodynamic and electric conditions. The model shows the flux of oxianions in terms of the difference between the transport number of As (V) in the boundary layer and in the membrane as a function of the current density. The model approaches to the experimental data when the transport number in the boundary layer is 1.5×10 -4 and 1.5×10 -5 for As (V)-H 2SO 4 and As (V)-Cu (II)-H 2SO 4 electrolytes, respectively. The validation of the model was made with published data of As (V) transport.
