Aiming at the problem of detecting method of ultraviolet fluorescence sulfur content of gasoline and diesel are researched in this paper;test explicitly set reagent and sample selection, the standard curve meth-od and test equipment control three key problems; the main factors of sample amount, reaction temperature and injection speed three accuracy affected by analysis and verification;through the test of E93# gasoline and 0# diesel two oil, and the maximum relative error is 0.45%and 0.24%respectively, the relative range is 0.89%and 0.44%; results show that: the determination of sulfur content of its analysis precision fully meet the re-quirements of the ultraviolet fluorescence method.
