- W152664459 abstract "활성탄소섬유(ACF; activated carbon fiber)를 흡착제로 사용한 고상추출법(SPE; solid phase extraction)으로 수용액 시료 중에 존재하는 특정화학물질(schedule chemicals)의 분석법을 연구하였다. 본 연구에 사용된 특정화학물질은 화학작용제류의 가수분해 생성물과 유사작용제로 사용되는 알킬포스포네이트류, 티오디글리콜 등 14종이었다. 분석을 위한 추출물의 실릴 유도체화 반응에서 피리딘을 사용하여 특히 3-quinuclidinol의 유도체화 반응 효율을 높일 수 있었다. 물 시료에서 아민류의 추출 회수율을 개선하기 위하여 SPE-ACF 튜브에 시료를 부하하기 전에 5% triethylamine/MeOH(1 mL) 용액으로 SPE-ACF 튜브를 세척한 후에 시료를 SPE-ACF에 부하하는 방법으로 추출 회수율을 증대시킬 수 있었다. 이 연구를 통해서 수용액 시료에서 특정화학물질을 신속히 검출할 수 있는 최적 조건을 선정하였다. study of the solid phase extraction (SPE) technique using activated carbon fiber (ACF) as a sorbent was carried out on the schedule chemicals in water. 14 different schedule chemicals, which are the hydrolysis products and simulants of chemical agents such as alkylphosphonate, thiodiglycol etc. were selected for the study. Pyridine was used as a promoter to increase the derivatization efficiency, especially to improve silylation of 3-quinuclidinol. To improve the recovery efficiency of amines in the water solution, 1 mL of 5% Et3N/MeOH was introduced into SPE-ACF before the water sample loading. Throughout this study, the optimum condition was established to detect rapidly above chemicals in water." @default.
