Selective fluoride removal in capacitive deionization by reduced graphene oxide/hydroxyapatite composite electrode.Capacitive deionization (CDI) is an emerging desalination technology with an environmental-friendly operation and energy-efficient properties.  However, activated carbon (AC) used for CDI electrode does not have a significant preference toward anions, leading to unnecessary energy consumption for treating fluoridated water.  Hence, we achieved selective fluoride removal in CDI system using a reduced graphene oxide/hydroxyapatite composite (rGO/HA), a novel fluoride selective electrode material.  Thus, this study suggests a novel electrode material for effective and selective fluoride removal in the CDI system.
