Abstract

This study was conducted to find out analytical method for diesel fuel using uv-spectrophotometer in water samples. The optimum wavelength, detection limit and recoveries for desel fuel extracted with n-pentane were 257nm, $100{\sim}800mg/l$ and $102{\sim}121%$, respectively. This method were stable for measuring concentrations of desel fuel for 1 hour at $20{\pm}1^{\circ}C$ condition.

관개수중에 함유된 경유정량을 위한 간이법을 개발하기 위하여 수행한 본 시험의 결과, n-Pentane를 이용하여 경유를 정량하기 위한 최적 파장은 257nm, 정량범위는 $100{\sim}800mg/l$이었으며, 시료에 함유된 경유의 회수율은 $102{\sim}121%$이었다. 실험 온도를 $20^{\circ}C$ 전후로 유지시킬 경우, 침출후 1시간까지 농도변화가 5% 이내로 휘발에 의한 실험 오차가 적었다.
