Synergic extraction of nickel(II) by 2-thenoyltrifuoroacetone and tribenzylamine in chloroform from perchlorate media
- 1. Pakistan Inst. of Nuclear Science and Technology, Islamabad (Pakistan)
Description
Synergic extraction of Ni(II) at ph 1 to 10 was studied using a mixture of 2-thenoyltrifluoroacetone (HTTA) and tribenzylamine (TBA) in chloroform. The synergist TBA enhances the extraction of Ni(II) by an order of 5 from ph 3 to 5. The synergic adduct was found to be Ni(TTA)2.2TBA. The equilibrium constants and stability constant were ascertained radiometrically. The influence of various cations and anions on the extraction of Ni(II) was examined under optimal conditions. Back extraction of the adduct species in different acids of varying concentrations was also studied. (author)
