Adsorption desalination of chloride ions on composite natural-synthetic materials: An approach for the reduction of chlorine corrosion in electrodeionization units
E-mail:
The release of chlorine in the electrodeionization (EDI) unit causes corrosion in the EDI unit, damaging ion exchange membranes and creating a safety risk for the workers. In this work, adsorption desalination of Cl- ions on low-cost composite synthetic-natural Jordanian materials were investigated as an approach to prevent the release of corrosive chlorine gas at the positive electrode. The percentage removal reaches 25% at 25 min shaking time to 55% at 120 min, in a single batch experiment. The values of △H°, △S°, and △G° indicate the favorability of physisorption. Zeolite and Pozzolana represent potential adsorbents of chloride.
