Abstract

Leather waste discharged from Shinpyung Changrim Industrial Complex contained 46.3 percent of carbon, and weight loss of leather waste about 50 percent was observed at $500^{\circ}C$ by thermogravimetric analysis. Chemically activated carbon [LW4AC] was made at activation temperature of $800^{\circ}C$ during 30 minutes in electric furnace. Iodine value and decoloration of methylene blue was 968 mg/g and 158 mL/g, respectively. We found that pore volume was more developed according to the increase in the ratio of $K_2CO_3/LW$.

신평장림 공단에서 배출되는 피혁폐기물은 46.3%의 탄소를 함유하고 있으며 열중량분석에 의하면 $500^{\circ}C$에서 중량손실이 약 50%이었다. $K_2CO_3$을 이용한 화학적 활성화법으로 $800^{\circ}C$에서 약 30분간 질소분위기 중에서 피혁폐기물을 원료로 한 피혁폐기물 활성탄[leather waste chemically activated carbon, LW4AC]을 제조하였다. 피혁폐기물 활성탄의 요오드 값, 메틸렌블루 탈색력은 각각 968 mg/g, 158 mL/g이었다. $K_2CO_3$와 피혁폐기물 혼합비 $[K_2CO_3/LW]$가 증가할수록 세공부피가 발달함을 알 수 있었다.
