In recent years, capacitive deionization (CDI) is reported as one of the emerging technologies developed with the purpose of water desalination. This work aims the use of supercapacitor electrodes for efficient removal of ions from water and contributes develepment of CDI technology. Towards the purpose, graphene based supercapacitor electrodes were developed and the use of these new materials for deionization purpose was explored in detail. The ion sorption behavior of the graphene electrodes developed from a commercially available graphene was analyzed at different electrical potentials and flow rates. Impact of operating parameters on sorption capacity was determined. At 20mL/min flow rate and 2.0V potential, the electrosorptive capacity of commercially available graphene electrodes could reach 12.5µmol/g. Our results showed that it is possible to develop supercapacitors from commercially available graphene material for the purpose of deionization
