초록
본 연구에서는 상업적으로 대량생산되어 값이 저렴한 유리섬유를 이용 새로운 저가의 활성탄소섬유복합체 필터를 제조하였다. 그리고 제조된 활성탄소섬유복합체 필터들의 비표면적, 세공크기분포, COD 제거율 그리고 페놀 제거율을 측정하여 비교·검토하였고, 수처리용 필터제조기술을 확립하였다. 필터제조시 ZnCL2 활성화법을 적용하였고, 활성화 최적조건은 활성화온도 400 ℃, 활성화시간 80 min, PAN 1.2 g이었고, 이 때 비표면적은 1610 m2/g이었고, 평균세공크기는 13.2 Å이었다. 제조된 활성탄소섬유복합체 필터들을 산업폐수, 페놀, 계면활성제 인공폐수에 적용하여 시간에 따른 유입수(Co)에 대한 유출수(C)의 비율(C/Co)로 흡착실험에 따른 제거율을 나타낸 결과 산업폐수의 경우 COD에 대한 C/Co(%)가 7%(원수농도: 45 ppm), 페놀에 대한 C/Co(%)가 5%(원수농도: 100 ppm) 그리고 계면활성제 인공폐수는 COD에 대한 C/Co(%)가 8%(원수농도: 120 ppm)까지 낮게 나타났고 흡착능이 좋은 것을 알 수 있었다.
The objectives of this study were to develop a process for manufacturing a new, low cost activated carbon fiber assemblies filter from glass fiber; to measure and compare the surface area, pore size distribution, COD and phenol removal ability of the manufactured activated carbon fiber assemblies filter; and to establish an application technique for the advanced watertreatment of various pollutants. Glass fiber based activated carbon fiber assemblies filter was manufactured using the ZnCl2 method. The optimum operating temperatures, time and the amount of PAN for activation were 400 ℃, 80 min and 1.2 g respectively. With these conditions, the BET surface area and average pore diameter were 1610 m2/g and 13.2 Å, reaspectively. The results showed the removal efficiency (C/Co) was 7% for 45 ppm of industrial wastewater concentration; the removal efficiency (C/Co) was 5% for 100 ppm of phenol concentration; and the removal efficiency (C/Co) of COD was 8% for 120 ppm of AOS (alpha-olefin sulfonate) concentration.
