This paper reports on the synthesis of a novel class of polymer inclusion membranes prepared by thermally‐induced phase separation using a mixture of two polymers: polyvinylidene fluoride (PVDF) and cellulose triacetate (CTA) plasticized by dioctylphtalate (DOP) and doped with organo–phosphoric compound: trioctylphosphine oxide noted (TOPO) as mobile carrier. The membranes (polymers − plasticizer − carrier) are characterized using physical techniques as well as Fourier transform infrared (FTIR) and thermo‐gravimetric analysis (TGA). All synthesized polymeric membranes are applied for investigation to the facilitated transport of Pb 2+ and Cd 2+ ions from aqueous nitrate source phase. All membranes are thermally stable up to nearly 178 °C. A study of the transport across a polymer inclusion membrane has shown that the lead transport efficiency is increased using TOPO as carrier. This study represents an interesting approach in the treatment of hydrometallurgical solutions using the TOPO neutral carrier mediated transport.
