The solvent extraction behaviour of tracer zirconium in the TTA-xylene system has been studied. By studying the effect of TTA concentration, extraction time, and acid concentration for HNO3 and HCl, optimum conditions of zirconium extraction are determined. It is found that zirconium is 98% extracted in one minute of extraction with 0.5M TTA in xylene from an 8M HNO3 solution. A plot of 1g D versus 1g [TTA] gives a straight line with a slope of 2. This suggests that the zirconium ion is hydrolyzed and is present as ZrO2+, zirconyl ion, in aqueous solutions.
