The simultaneous extraction and stripping of mercury(II) from petroleum produced water via hollow fiber supported liquid membrane (HFSLM) was examined. Optimum conditions for extraction and stripping were pH 1 in feed solution, 5% (v/v) Aliquat 336 in the liquid membrane and 0.05 M thiourea in the stripping solution. Percentages obtained for extraction and stripping of mercury(II) were 96.8% and 92.5% which were below the legislation limit of 5 ppb. The overall mass transfer resistance (R) was 7.286 x 10(2) s/cm. Results showed that the mass transfer model fitted in well with the experimental data. (C) 2014 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
