Experimental and theoretical mass transfer transient analysis of copper extraction using hollow fiber membrane contactors

► The current research article covers the extraction equilibria and non-dispersive extraction of copper (II) with 1,1,1-trifluoro-2,4-pentanedione diluted in different organic solvents. ► HFMCs are modelled based on axial-radial approach which has then replaced successfully by single-fiber flow model. ► From the experimental work regarding extraction equilibria, it is found that copper extraction is instantaneous at the interface as Ha was found to be greater than 3 and therefore does not play a significant role in controlling the mass transfer rate of copper through the porous membrane. And when TFA is diluted in MIBK, it gives better values of P than decanol and TD as diluents. ► Dynamic model was validated for recycled-based continuous non-dispersive extraction of copper using HFMC under a range of copper initial concentration in aqueous phase under different hydrodynamic conditions and both flow configurations. Simulation envisaged the performance of HFMC for efficient and fast extraction of Cu (II).
