Abstract

The purpose of this paper is to use lignin. Lignin was obtained by digestion of Korean pine wood, purified, and identified. After carbonizing lignin by con $c-H_2SO_4$, the resulting carbon was converted into active carbon by activating it in the electric kiln. The adsorptivity of this active carbon was obtained by measurement with a spectro-photometer. It has been found as a result that adsorption power is 89%.

1기압하에서 한국산 소나무로부터 lignin을 추출할 수 있는 실험실에서의 최적 조건을 구했고, m.p, 증색반응, IR등의 방법으로 순수한 lignin임을 확인했다. 추출한 순수 lignin을 진한 황산으로 탄화한 후 전기로 속에서 650$^{\circ)C$로 공기 부활하여 활성탄을 제조하였다. 이 활성탄의 광전 비색계에 의한 흡착능을 조사한 결과 89%였다.
