Separation of strontium from simulated waste in K2SO4/nitrate medium containing Sr2+, Eu3+, Ce3+, Pd2+, Rh3+, Ru3+, UO22+, Fe3+, Cr3+, Ni2+, Al3+, Ca2+ and Cs+, by strongly basic anion exchanger

In this work Strontium was separated selectively form, Pd2+, Ni2+ and Ca3+ using anionic resins of Amberlite type IRA-900 and IRA-410 from nitrate medium. The Separation of strontium by strongly basic anion exchangers IRA-410 and IRA-900 from simulated waste containing, Sr2+, Eu3+, Ce3+, Pd2+, Rh3+, Ru3+, UO22+, Fe3+, Cr3+, Ni2+, Al3+, Ca2+, and Cs+, in K2SO4/nitrate medium which adsorbed as strontium sulphate complex was achieved through ligand-ligan exchange. The elution of strontium carried out via ''loading'' the column with a solution of 0.03N EDTA in presence of 0.1N NaNO3 at pH7 where Sr2+ has low K-d value. An inductively Coubled Plasma - Optical Emission Spectrometry (ICP - OES) of ARL type model 3520, was used for elemental analysis.
