Abstract

The efficiency of polymer inclusion membranes (PIMs) for gold extraction, particularly using Aliquat-336 as a carrier, has been extensively studied. The membrane was fabricated by combining poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) with dioctyl phthalate (DOP) and varying concentrations of Aliquat-336 (5, 10, 15, 20, and 25 wt.%). The optimal formulation, incorporating 20 wt.% Aliquat-336 (M5), demonstrated significant improvements in ion exchange capacity (IEC) extraction rates, achieving an impressing 1.697 meq/g and 95.96% extraction efficiency, respectively.
