C14O2 의 흡수제로서 폐닐에칠아민과 하이아민베이스의 비교 = Comparison of Phenyl Ethylamine and Hyamine Base as an Absorbent of Carbon Dioxide

다국어 초록 (Multilingual Abstract)

In order to compare their absorption abilities of carbon dioxide, Hyamine base and phenyl ethylamine were employed in wet combustion experiments. The known content of liver lipid and uniformly mixed palmitic acid-C^(14) were oxidized with sulfuric acid and phosphoric acid. Carbon dioxide produced was trapped by the amines tested through thin tube. The amines absorbed carbon dioxide were mixed with diotal scintillator and counted by liquid scintillation counter.
The counting efficiencies and radioactivity recoveries were 50 to 60 % and nearly 100 % for both amines. However, the absorption ability of carbon dioxide by phenyl ethylamine was about two times that of Hyamine base.
This technique would not be necessary for the counting of liver lipid of swim, because the efficiencies were not increased and counting accuracies were similar to those of direct counting.
