Activated carbon is the most common electrode material used in electrosorption processes such as water desalination with capacitive deionization (CDI). In the present work, we study ion selectivity from salt mixtures with two different monovalent ions, chloride and nitrate. We run adsorption experiment in microporous carbons (i.e., without applying a voltage), as well as electrosorption experiments (i.e., based on applying a voltage between two carbon electrodes). Our results show that i. during adsorption and electrosorption, activated carbon removes much more nitrate than chloride; ii. at equilibrium, ion selectivity does not depend strongly on the composition of the water, but does depend on charging voltage in CDI; and iii. during electrosorption, ion selectivity is time-dependent. We modify the amphoteric Donnan model by including an addnl. affinity of nitrate to carbon. We find good agreement between our exptl. results and the theory. Despite this decrease, the affinity-effect for nitrate continues to play an important role also at a high voltage. In general, we can conclude that our work provides new insights in the importance of carbon-ion interactions for electrochem. water desalination. In the experimental materials used by the author, we found Sodium chloride(cas: 7647-14-5Product Details of 7647-14-5)
