Abstract. The efficiency of polymer inclusion membranes (PIMs) for gold extraction, particularly using Aliquat-336 as a carrier, has been extensively studied. The membrane were fabricated by combining poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) with dioctyl phthalate (DOP) and varying concentrations of Aliqua-336 (5,10,15,20,25 wt.% Aliquat-336). The optimal formulation, incorporating 20 wt.% Aliquat-336 (M5), demostrated significant improvements in ion exchange capacity (IEC) and extraction rates, achieving an impressing 94.74% extraction efficiency.
Keywords: polymer inclusion membrane (PIMs); gold extraction; poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP); dioctyl phthalate (DOP); aliquat-336
