Highly mesoporous activated carbon electrode for capacitive deionization

---

Abstract.
The capacitive deionization (CDI) technology using different activated carbon electrodes was investigated
to desalinate. The effect of specific surface area and pore structure of the activated carbon electrodes on
the amount of ions removed in CDI was demonstrated. A highly mesoporous activated carbon (ACk2) was
chosen to study desalination performance in detail. It is found that the electrosorption kinetics follows
pseudo-first-order model. The electrosorption isotherm investigation shows that Langmuir isotherm
can better describe experimental data. The maximum electrosorption capacity (qm) of the ACk2 electrode
decreases from 10.9 to 9.4 mg/g when solution temperature increases from 289 to 308 K. Good reproducibility
in regeneration phase was achieved because of highly mesoprous distribution of ACk2 electrodes.
