Recovery of copper(II) through polymer inclusion membrane with di (2-ethylhexyl) phosphoric acid as carrier from e-waste

▸ Permeation of Cu(II) ions through PIM was carried out using D2EHPA as carrier. ▸ The stability of the membrane was constant for ten cycles, each cycle for 12 h. ▸ The valuable Cu(II) ions were recovered from digested e-waste samples.
