✦ Synopsis

AbStiWt 3-Nitrofluoranthene and 1-nitropyrene in suspended particulate matter can be determined precisely by liquid chromatography with fluorescence detection (392 nm excitation, 502 nm emission). The nitro polynuclear aromatic hydrocarbons (nitro-PAHs) are reduced to the corresponding ammo compounds with aqueous sodium hydrosulfide solution. Other nitro-PAHs do not interfere. Calibration graphs are linear at least over the range of 0.06-1.2 ng of nitro-PAH. Relative standard deviations (n = 10) are 3.4% and 3.9% for 1.2 ng of 3nitrofluoranthene and l-nitropyrene, respectively.

High-performance liquid chromatography on a Zipax SAX column with U.V. detection at 200 nm gives precise results for bromide. Chloride, bromate, nitrite, nitrate, iodide, thiocyanate and various cations do not interfere; prior treatment with activated charcoal removes interfering organic compounds.
