Occurrence of re-adsorption in desorption cycles of capacitive deionization

This research explored the occurrence of re-adsorption that may impose negative impact on electrode regeneration in capacitive deionization (CDI). Among the tested operational modes, polarity reversal was found to deliver faster salt desorption than a conventional short circuit and reduction of cell...

Description
Summary:This research explored the occurrence of re-adsorption that may impose negative impact on electrode regeneration in capacitive deionization (CDI). Among the tested operational modes, polarity reversal was found to deliver faster salt desorption than a conventional short circuit and reduction of cell voltage to 0.3V. Earlier occurrence of re-adsorption was observed when the CDI system was operated under a higher reversed discharge voltage. An optimized polarity reversal at 1.2V followed by a short circuit is considered as a promising approach for efficient CDI operations for practical engineering use.
