Abstract

This experiment was carried out with the purpose of testing nickel and copper adsorption abilities of multi wall carbon nanotube (MWCNT) and activated carbon. In the acidic condition, only MWCNT was effective for removing nickel and copper ion in the aqueous phase while activated carbon rarely remove them. The MWCNT and heavy metals adsorption reaction followed pseudo-first order kinetic. When the initial pH value was neutral (pH=7), nickel was rapidly removed by MWCNT and activated carbon in 4 hr (99.02 %, 80.30 %). Also, copper ion was rapidly removed by both adsorbents in 4 hr when the initial pH was 7 (100 %, 99.73 %). Increasing of adsorbent dosages affect the pH evolution and heavy metal ions removal (0 ~ 99%). Also, oxidation pretreatment enhanced the adsorption efficiency of MWCNT.

본 연구는 탄소나노튜브(MWCNT)와 활성탄을 이용한 니켈과 구리의 흡착특성을 평가하였다. 산성조건에서 활성탄의 제거성능이 낮은 반면, MWCNT만 니켈과 구리를 흡착 제거하는데 효율적이었다. MWCNT와 중금속의 흡착반응은 유사 일차반응식을 따랐다. 초기 pH가 중성일 때, 니켈은 MWCNT에 의해 신속히 제거되었고, 활성탄은 4시간에 각각 99.02%와 80.30%를 나타냈다. 또한, 구리이온은 초기 pH가 중성일 때 4시간내에 효율적으로 제거되었다. 흡착제 주입량을 증가함에 따라 pH가 증가하였고, 중금속 제거율도 증가하였다. 또한, 산화 전처리 공정은 MWCNT의 중금속 제거율을 증가시켰다.
