| 摘 要： | 本报告对溶剂萃取海水中微量油的荧光分光光度法进行了系统研究。作者总结了两种测油溶剂体系、环己烷、正己烷、石油醚和二氯甲烷一正己烷、四氯化碳一正己烷，氟里昂一环己烷六种方法，系统考察了各法的精密度、回收率、检出限等，并实测了海水样品，其中正己烷，石油醚、氟里昂一环己烷法用于海水检测是作者提出的，而且还考察了四氯化碳、二氯甲烷、氟里昂对荧光熄灭的影响，提出了环己烷、石油醚、氟里昂一环己烷法更实用可行。

| Abstract: | In the paper, some methods have been studied systematically using solvent extracts by fluorescence spectroscopy for determining a small amounts of petroleum oil in sea water.The six kinds of methods of solvent extracts in two large systems have been summed up by the writers. They are cyclohexane, n-hexane, petroleum ether, dichloromethane-n-hexane, carbon tetrachloride-n-hexane and freon-cyclohexane. The precisions, recoveries of all kinds of methods and the detected limit have been examined. The samples of sea water were detected in practice. The methods of n-hexane, petroleum ether and freon-cyclohexane among them were proposed by the authors. The influence of carbon tetrachloride, dich-Ioromethane and freon on fluorescence quench was also examined. The paper shows the methods of cyclohexane, petroleum ether and freon-cyclohexane can be in common use. |
