활성탄의 재생 목적으로 cadmium 흡착 활성탄에 대하여 용출액을 염산 수용액으로 하여 정전류 조건에서 전기삼투 실험을 수행하였다. 전기삼투투과 계수, 전기삼투 물-이동 효율 및 겉보기 전기전도도의 값은 시간에 따라 변화하고 H+ 이온은 양극에서 음극 쪽으로 이동하며 cadmium 제거효율은 90% 이상임을 알 수 있었다.
For the purpose of activated carbon regeneration, electro-osmosis tests were conducted on activated carbon specimens loaded with cadmium under constant currents using hydrochloric acid aqueous solution as a purge solution. Electro-osmotic permeability, electro-osmotic water-transport efficiency and apparent conductivity values were time-dependent. The results show that H+ ions move from anode to cathode compartment and the cadmium removal efficiency is over 90%.
