利用PAHs具有高的荧光量子产率,同步荧光法具有快速、灵敏、选择性较好的优点,建立了同时测定水溶液中溶解态蒽和芘的方法。所建方法测定蒽和芘的线性范围分别为1.0×10^-8~2.0×10^-7mol/L和5.0×10^-9~3.5×10^-7mol/L.检出限分别为1.69×10^-9mol/L、8.42×10^-10mol/L,相对标准偏差分别为2.90%、2.34%(n=5)。运用所建方法尝试了自来水样品的测定。
A synchronous fluorimetry has been established for simultaneous determination of dissolved anthracene and pyrene in an aqueous solution. The linear ranges for the determination of dissolved anthracene and pyrene were 1.0 × 10^-8 -2.0× 10^-7 and 5.0 × 10^-9 - 3.5 × 10^-7 mol/L, their detection limits were 1.69 × 10^-9 and 8.42 × 10^-10 mol/L, and their relative standard deviations were 2.90% and 2.34% (n = 5), respectively. Satisfactory results were obtained by the method for the determination of artificial samples in tap water.
