Abstract
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. In this experiment, optimum percentages of mercury (II) extraction and stripping were obtained at flow rates for both feed and stripping solutions of 100 mL/min using a single–module operation for a period of 40 min. 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 102 s/cm. Results showed that the mass transfer model fitted in well with the experimental data.
