AB - This work presents the investigation of Ni(II) extraction from aqueous solution through pseudo-emulsion based hollow fiber strip dispersion (PSEHFSD) containing the mixture 2-hydroxy-5-nonylbenzaldehyde oxime+di(2-ethylhexyl) phosphoric acid/Exxsol D100 as extractant in the form of a pseudo-emulsion with H₂SO₄. The organic and aqueous strip phases are separated when the stirring device is stopped. The permeation of Ni(II) is investigated as a function of various experimental variables: hydrodynamic conditions, feed pH, extractants mixture concentration in the pseudo-emulsion, initial Ni(II) concentration in feed phase, H₂SO₄ concentration in the pseudo-emulsion as strippant. In PEHFSD, pseudo-emulsion is an emulsion that is formed temporarily between organic and stripping solutions. In this investigation, feed was circulated through the lumen side in counter-current mode. The selectivity of 2-hydroxy-5-nonylbenzaldehyde oxime+di(2-ethylhexyl) phosphoric acid/Exxsol D100 based PEHFSD toward different metals was also examined.
