Model of electrodialysis process associated with organic adsorption

A convective-diffusion model was developed to predict the performance of both electrodialysis (ED) and adsorption on species in an aqueous solution. The quasi-steady-state model was solved by finite difference to assess the effects of a packed bed of graphite on separation of an univalent electrolyte and an organic compound in an ED cell. A sensitivity analysis of parameters in the model was also performed. Comparison of simulation results with experimental data of 2-Naphthol (2-C10H7OH) in sodium chloride solution was used for this case study. The model satisfactorily predicts 2-Naphthol removal at the 95% confidence level.
