•HFSLM can successfully extract and strip mercury ions from petroleum produced water.•A high percentage of extraction was obtained reaching 99.73%.•A high percentage of stripping was obtained reaching 90.11%.•The mathematical model for separation was based on the conservation of mass.•Average deviation for feed and stripping predictions were 1.5% and 1.8%.
The separation of mercury(II) from petroleum-produced water from the Gulf of Thailand was carried out 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 noted was 94.92% taking account of both extraction and recovery prospects. The model for this separation developed along a combined flux principle i.e. convection–diffusion–kinetic. The results showed excellent agreement with theoretical data at an average standard deviation of 1.5% and 1.8%, respectively.
