Influence of electrochemical properties of silica sol on the electrodialysis performances |
| 초록 |
Negative charged silica sol is known to lead to fouling in electrodialysis, as a result of its adsorption on the surface of an anion exchange membrane. In this study, the properties of silica sol were characterized in terms of electrochemical properties in order to predict its effects on the performance of the electrodialysis and the critical coagulation concentrations of silica sol were determined as functions of electrolyte properties. In the electrodialysis of NaCl solution containing silica sol with various concentrations of calcium chloride, the behaviors of silica sol during and after electrodialysis were examined. The results show that the behavior of silica sol depends on the colloidal stability in the various electrolyte concentrations and affect electrodialysis performances. |
