AbstractA photochemical vapor generation system coupled to an inductively coupled plasma optical emission spectrometer (ICP-OES) was used for the determination of inorganic mercury in high salinity water arising from offshore petroleum exploration platforms, i.e., production water (PW). The system comprised a 17 W UV grid lamp for photogeneration along with two gas/liquid separators functioning in tandem to minimize aerosol transport into the plasma. Analytical conditions, including type and concentration of low molecular weight organic acid, UV exposure time and solution pH were optimized. Continuous-flow processing of a sample containing 1.63 mol L-1 formic acid at pH 2.0 for a UV irradiation time of 30 s permitted Hg(II) to be determined based on the method of additions. Procedural limits of detection and quantification of 1.2 and 4.0 µg L-1, respectively, were achieved. Recoveries of 10 - 40 µg L-1 Hg(II) spikes added to real samples ranged from 79 to 121%.
