낮은 에너지 γ-선 흡수법에 의한 Hydrocarbon중의 유황 정량 제1 보

Abstract

물질의 Mass absorption coefficient 차이를 이용하여 Hydrocarbon중에 불순물로 포함되어 있는 유황을 신속 정확히 정량할 수 있는 방법을 이론적으로 고찰하였다. 유황, 수소 및 탄소의 γ-선에 대한 Total attenuation coefficient는 근사식을 써서 계산한다. γ-선의 에너지 범위는 10∼80KeV정도가 적당하고 Gamma-emitting isotope로서는 ²⁴¹Am, ¹??Tm, ²?²Cf, ²³²Th, ²³?U등이 실제 분석에 유용할 것이다.

Possibility of a rapid and acurate determination of Sulfur in hydrocarbon was checked theoretically by means of its particular mass absorption coefficient. Total attenuation coefficient of electrom-agnetic radiation in Sulfur, Hydrogen and Carbon were calculated by means of the approximation formula. Useful γ-ray energy ranges were from 10 to 80 KeV, so that only a weak gamma-emitting radioisotopes such as ²⁴¹Am, ¹??Tm, ²?²Cf, ²³²Th, ²³?U seem to be very useful for the practical analysis.
