In this work, the possibility of separation of Zn2+and Cd2+metal ions from chloride (brine) solutions was exam-ined. For this purpose, simple solvent extraction (SX) experiments by di-2-ethylhexyl phosphoric acid (D2EHPA) in kerosene as a diluent was performed on synthetic and industrial chloride solution obtained from brine leaching of zincfilter cakes (by-product of zinc hydrometallurgical processing). The optimal conditions for separation were determined. The zinc extraction efficiency was 99％with negligible co-extraction of cadmium. Therefore, a high ΔpH0.5 value for Zn(Ⅱ) and Cd(Ⅱ) was achieved. FT-IR and slope analysis indicated that ZnClA?3HA and CdClA?3HA species were probably extracted.
