Keywords:hydrophobic, ionic liquid, TPEN structure, Cd2+

A novel hydrophobic ionic liquid including TPEN structure ((IL-TPEN)+NTf2-) was successfully synthesized and its extraction behavior of Cd2+ and Zn2+ from nitric acid solution was investigated. The maximum separation factor of Cd2+ and Zn2+ was obtained as 8 at pH 2.
