dc.description.abstract액상 유해 화합물 누출 사고시 사용하는 건토/모래에 비하여 큰 수착용량을 가지는 새로운 소재를 발굴하기 위하여 9종의 과립형 광물 시료들에 대한 에탄올 수착 실험을 수행하였다. 수착 성능을 평가하는 표준화된 방법이 부재하여, 비침투성 바닥에 고인 액상 화합물에 적용 가능한 수착용량 및 수착속도를 결정하는 시험법을 제안하였다. 수착용량은 마사토(0.02 g/g)에 비하여 다양한 기공 구조들이 발달한 팽창질석(1.64 g/g), 진주암(0.57 g/g), 난석(0.48 g/g), 규조토(0.34 g/g)에서 큰 값을 가졌다. 질소 흡착 실험을 통하여 nm 크기의 미세기공에 비해서 μm 이상의 큰 기공에서 효율적인 수착이 발생함을 확인하였다. 또한 침수 시간에 따른 수착용량 변화를 측정하여 수착이 10 분 이내에 대부분 이루어짐을 확인하였다.-
dc.description.abstractEthanol sorption experiments were performed for 9 kinds of particulate minerals to find novel sorbent material with a higher sorption capacity than dried soil or sand used in the spill accident of liquid hazard chemicals. Since there was no standard method for the sorption evaluation, an experimental protocol was proposed to determine sorption capacity and rate for spilled hazard chemicals over nonpermeable floor. The sorption capacity exhibited higher values for the porous minerals of expanded vermiculite (1.64 g/g), perlite (0.57 g/g), orchid stone (0.48 g/g) and diatomite (0.34 g/g) than 0.02 g/g of masato. Macropores larger than 1 µm were found more responsible for the sorption than nm-sized micropores by N2 adsorption measurements. Furthermore, the sorption was found to reach to a steady state within 10 minutes from the dependence of an immersing time on the capacity-
