The simultaneous extraction and stripping of mercury(II) from petroleum produced water via hollowfiber supported liquid membrane (HFSLM) was examined. Optimum conditions for extraction andstripping were pH 1 in feed solution, 5% (v/v) Aliquat 336 in the liquidmembrane and 0.05 Mthiourea inthe stripping solution. Percentages obtained for extraction and stripping of mercury(II) were 96.8% and92.5% which were below the legislation limit of 5 ppb. The overall mass transfer resistance (R) was7.286 102 s/cm. Results showed that themass transfer model fitted in well with the experimental data.
