The study was performed to understand the feasibility of graphite felt for electro-enhanced removal ofperchlorate ions through capacitive deionization process (CDI) in aqueous solution. The cyclicvoltammetry studies indicated that the perchlorate ions neither get oxidized nor reduced under theoperating conditions for the applied potential range of 1.5 V. The effect of voltage,flow rate, perchlorateconcentration, pH of the solution and temperature on the electrosorption was studied. Theelectrosorption capacity increased with increasing applied potential,flow rate and perchlorateconcentration. The change in pH significantly affected the removal efficiency due to competitive ioniceffect. The increase in temperature had a negative impact on the electrosorption capacity. Langmuirmodel was found to be a betterfit than the Freundlich model and the maximum electrosorption capacitywas found to be 21.1 mg g 1. It was observed that electro-enhanced adsorption followed pseudofirstorder kinetic model with a rate constant of 0.45 min 1 for an initial concentration of 1000 mg L 1operated at 1.5 V. Moreover the graphite felt exhibited good repeatability of the electrosorption processand affinity toward perchlorate ions. Thus it can be concluded that the graphite felt electrode can bepotentially used for electrosorptive removal of perchlorate ions from the aqueous solution.
