Abstract	Reports a study in which the separation of mercury(II) from petroleum-produced water from the Gulf of Thailand was conducted using a hollow fiber supported liquid membrane system (HFSLM). Optimum parameters for feed pretreatment were 0.2 M HCl, 4% (v/v) Aliquat 336 for extractant and 0.1 M thiourea for stripping solution. The best percentage obtained for extraction was 99.73% and for recovery 90.11%, respectively. The overall separation efficiency was 94.92%. The model for this separation developed along a combined flux principle i.e. convection–diffusion–kinetic. Results revealed excellent agreement with theoretical data at an average standard deviation of 1.5% and 1.8%, respectively.
