Synergic Extraction of Titanium (IV) with the New Solvent Tri-iso-amyl Phosphate (TAP) and Thenoyltrifluoroacetone (TTA)

The extraction of Ti (IV) from aqueous hydrochloric acid solution was investigated by using three different solvent systems: thenayltrifluoroacetone (TTA), a new solvent tn-iso-amyl phosphate (TAP)and a mixture of TTA and TAP, all diluted with carbon tetrachloride. An optimum of 90.34% and 97.45 %...
