Abstract
음이온세제와 비이온세제의 혼합물에서 alkylbenzene sulfonate 계통의 음이온 세기가 NMR법에 의해서 정량되었다. 음이온세제와 비이온세제의 혼합물에 대한 NMR 스펙트럼에서, 벤젠 그룹은 6.5∼8ppm에서 중첩된 피크를 보여주나 sampling 후의 벤젠 그룹은 7∼8ppm에서 두개의 doublet을 보여준다. 검량선은 음이온세제의 벤젠그룹과 초산의 메칠그룹의 상대적인 면적비에 의해서 작성되었다. (초산은 내부표준물로 사용되었다.)

Amounts of alkylbenzene sulfonate (ABS) in the mixtures of anionic and nonionic detergents were determined by nuclear magnetic resonance (NMR) method. In the NMR spectrum of anionic and nonionic detergents, benzene group showed peaks overlapping at 6.5∼8ppm, but after sampling, benzene group showed two doublet at 7∼8ppm. Calibration curve was obtained by relative ratio of area for benzene group in anionic detergent to that for methyl group in acetic acid(acetic acid was used as the internal standard).
