분변토를 이용한 VOCs 흡착에 관한 기초연구 = A Fundamental Study on the Adsorption Capacity of VOCs by Earthworms Cast

다국어 초록 (Multilingual Abstract)

This study was carried out two point view that reuse of sludge and adsorption of benzene, toluene and o-xylene of VOCs in cast, carbonized cast and activated carbon. The cation exchange capacity of cast and carbonized cast were 59.2, 112 meq/l00g, respectively. The specific surface were 560, 800 ㎡/g, respectively. The average removal rates of benzene by 50g cast of 50% hydrous cast, anhydrous cast, carbonized cast, activated carbon were 15.0, 41.2, 88.2, 99.4% in 60min retention time. The average removal rates of toluene by 50g cast of 50% hydrous cast, anhydrous cast, carbonized cast, activated carbon were 12.5, 34.2, 88.2, 99.5% in 60min retention time. The average removal rates of o-xylene 50g cast of 50% hydrous cast, anhydrous cast, carbonized cast, activated carbon were 8.8, 28.5, 84.8, 98.1% in 60min retention time. The adsorption efficiency of test absorbent was in order of benzene > toluene > o-xylene.
