“…Yet, only a few models have been generated to describe the transport of target ions on both feed and strippant sides. Jagdale et al 28 , for example, developed a mathematical model for predicting the extraction and stripping of neodymium(III) via HFSLM. The model was implemented by considering mass accumulation, convection and diffusion but chemical reaction was ignored.…”

This work presents the elimination of arsenic ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). Results demonstrate that arsenic ions in synthetic wastewater can be successfully treated to meet the wastewater standard as formulated by the Ministry of Industry and the Ministry of Natural Resources and Environment, Thailand. The discharged limit of arsenic from industrial wastewater must not be greater than 250 ppb. In a single-step operation, arsenic ions are extracted and stripped. Percentages of extraction and stripping proved to be 100% and 98%, respectively. Optimum conditions found proved to be 0.68 M Aliquat 336 dissolved in toluene as the liquid membrane, at pH 12 of feed solution, having a mixture of HCl and thiourea as the synergistic strippant, and flow rates of both feed and strippant solutions of 100 mL/min. A mathematical model, developed to predict the final concentration of arsenic ions in feed and strippant solutions, is seen to fit in well with the experimental results.

This work presents the elimination of arsenic ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). The effects of extractants, pH of feed solution, strippant solutions, and flow rates of feed and strippant solutions are duly investigated. Results demonstrate that arsenic ions in synthetic wastewater could be treated to comply with the standard of wastewater discharged (< 0.25 mg/L) via HFSLM. Percentages of extraction and stripping proved to be 100% and 98%, respectively. Thus, in a single-step operation, arsenic ions are extracted and stripped, using 0.5 M Aliquat 336 as the extractant, at pH of feed solution of 12, with a mixture of thiourea and hydrochloric acid (0.5 M each) as the synergistic strippant solution, and flow rates of both feed and strippant solutions of 100 mL/min. A mathematical model has also been developed to predict the final concentration of arsenic ions in feed and strippant solutions. The results predicted by the mathematical model fit in well with the experimental results.
