Abstract

A technique to measure the adsorption characteristic of surface area and pore size distribution is proposed and its performance is examined. While the existing equipment utilizes liquid nitrogen, the proposed uses carbon dioxide at the room temperature leading to the small measuring device with easy operation and short measurement time. The performance of the device has been examined with micro-particle carbon cryogel and bamboo activated carbon. The results from the proposed device compared with those of the adsorption apparatus indicate that the measurement of meso-porous material is comparable but micro-porous material gives some error.

흡착제의 흡착특성인 흡착표면적과 세공크기를 수정진동자를 이용하여 측정하는 방법을 제안하고 그 성능을 조사하였다. 액체질소를 활용하는 기존의 방법에 비해 상온에서 이산화탄소를 이용하기 때문에 장치가 소형이고, 조작이 간편하며 짧은 흡착시간 내 측정이 가능한 이점을 가지고 있다. 마이크로 입자의 카본 크라오젤과 대나무 활성탄에 대해 흡착특성을 측정한 측정치를 흡착능 측정기로 측정한 측정치와 비교한 결과 메조세공의 흡착제에 대해서는 유효한 측정치가 얻어진 반면 마이크로 세공의 입자에서는 다소 큰 오차를 나타내었다.
