Abstract

Desalination effects of Capacitive deionization(CDI) process using activated carbon $TiO_2$ composite electrode. In this study, we made the activated carbon electrod and activated carbon $TiO_2$ composite electrode, which analysed at cyclic voltammetry and charge-discharge. The results measured for discharge capacitance in cyclic voltammetry were 125 F/g in activated carbon electrode and capacitance of activatd carbon composite electrode was increased about two time, 243 F/g. The $TiO_2$ content of activated carbon composite electrode was 10 wt.%. When it was added wtih TiO2, electric double layer adsorption content was increased, so it was increased 25% in ion removal ratio of activated carbon electrode.

$TiO_2$가 첨가된 탄소복합전극을 제조 Capacitive deionization(CDI)에서의 제염효과에 대하여 고찰하였다. 본 연구에서는 탄소전극과 탄소복합전극을 제조하여 순환전류전압법과 충전-방전 평가를 하였으며 이때의 이온제거율에 대하여 고찰하였다. 순환전류전압법으로 1 mV/s의 전위주사속도에서 측정한 결과 탄소전극은 125 F/g, 탄소복합전극의 축전용량은 243 F/g으로 2배 증가됨을 확인하였다. 탄소복합전극의 $TiO_2$의 함량은 10 wt.%로 고정하였으며 $TiO_2$가 첨가됨에 따라 전기이중층 흡착량이 증가되어 이온제거율이 탄소전극보다 25% 증가되었다.
