초록

본 연구에서는 공기청정기 필터용 활성탄의 아세트알데하이드 제거 특성이 금속 촉매 첨착 및 관능기 도입 방법을 사용하여 조사되었다. 야자각 차의 KOH 활성화를 통해 고 비표면적(1700 m2/g)과 미세기공이 발달한 활성탄을 제조하였으며, 금속촉매 첨착과 관능기 개질을 위해 침지 후 기공 내 건조조건에 따른 첨착 효율을 조사하였다. 제조된 활성탄의 물성은 비표면적 및 기공 분석(BET), 유도결합 플라즈마 분광 분석(ICP), 유기 원소 분석(EA) 및 푸리에변환 적외선 분광 분석(FT-IR) 등을 통해 분석하였으며, 활성탄 성능 확인을 위해 침지 농도에 따른 아세트알데하이드 흡착성능을 가스크로마토그래피(GC)로 분석하였다. 첨착용액의 농도가 증가함에 따라 금속촉매 첨착량은 증가하였으며, 비표면적은 감소하는 경향을 보였다. 각 금속촉매 첨착 및 표면개질 활성탄의 파과시험 결과 MgO10@AC, CaO10@AC, EU10@AC, H-U3N1@AC 조성에서 우수한 아세트알데하이드 흡착성능을 보여주었다. 흡착성능이 가장 뛰어난 MgO10@AC에 대해 파과 시간은 533.8 분, 흡착량은 57.4 mg/g으로 측정되었으며, 이는 활성탄에 나노 크기의 MgO 촉매를 첨착할 경우 아세트알데하이드의 카보닐기와 상호작용하여 흡착성능이 개선됨을 알 수 있었다.

In this study, the acetaldehyde removal characteristics of activated carbon (AC) for air purifier filters were investigated using metal catalysts-impregnation and functional group-modification method. The AC with a high specific surface area(1700 m2/g) and micropores was prepared by KOH activation of coconut charcoal and the efficiency of catalyst and functional group immobilization was examined by varying the drying conditions within the pores after immersion. The physical properties of the prepared activated carbon were analyzed by BET, ICP, EA, and FT-IR, and the acetaldehyde adsorption performances were investigated using gas chromatography (GC) at various impregnation and modified conditions. As the concentration of impregnation solution increased, the amount of impregnated metal catalysts increased, while the specific surface area showed a decreasing trend. The adsorption tests of the metal catalyst-impregnated and functional group-modified activated carbons revealed that excellent adsorption performance in compositions MgO10@AC, CaO10@AC, EU10@AC, and H-U3N1@AC, respectively. The MgO10@AC, which showed the highest adsorption performance, had a breakthrough time of 533.8 minutes and adsorption capacity of 57.4 mg/g for acetaldehyde adsorption. It was found that the nano-sized MgO catalyst on the activated carbon improved the adsorption performance by interacting with carbonyl groups of acetaldehyde.
