บทคัดย่อ: The removal and recovery of paraquat from an aqueous solution using a hollow fiber supported liquid membrane (HFSLM) was performed. The extractant was Di-(2-ethylhexyl) phosphoric acid (D2EHPA) which was dissolved in kerosene, whereas the recovery solution was a hydrochloric acid solution. It was found that the pH concentration of D2EHPA, concentration of hydrochloric acid at 8, 4% (v/v), and 1.0 M, respectively, were the optimum conditions. In the one-through mode, 70% and 68% of extraction and recovery, respectively, were achieved, while 99% extraction and recovery were obtained in the circulated mode. In addition, the mathematical model can predict the concentration of paraquat in raffinate solution with different paraquat concentrations and flow rates of feed solution with the R2 of 0.923 and 0.843, respectively. © 2020 Taylor & Francis Group, LLC.
