Atomic fluorescence spectroscopy coupled with cold vapour (CV-AFS) was used to analyse mercury content in process water from oil and gas industry. Both external calibration and standard addition method were applied to determine the concentration. The result obtained shows concentration of mercury (Hg) in standard addition was 561.31 ppt, while the concentration in external calibration was 311.9 ppt. Both of the concentrations obtained were below maximum limit of Hg content in water (100 ppb).
