Abstract: Chromosorb 102 impregnated with Cyanex 923 was used as a stationary phase in the extraction chromatographic separation of lanthanides, U(VI), Th(IV) and Zr(IV). Batch studies were carried out to investigate the uptake behaviour of these metal ions, along with few other metal ions. The effect of different parameters like equilibration time, concentration of acid, metal ions and extractant has been studied. The distribution data has been used to develop suitable eluting agents. The sorbing and desorbing capacity of the column for U(VI), Th(IV) and Zr(IV) was determined. Results indicate an insignificant change in the efficiency of the column up to 10 such cycles. The practical utility of the column has been demonstrated by the recovery of around 95% of U(VI), Th(IV) and Zr(IV) from allanite sample with a purity of around 97%±2%. © 2013 The Authors.
