Description
The applicability of MnO2-resin for the selective separation of Ra(II) from aqueous solutions containing also U(VI) and Eu(III) has been investigated as a function of solution pH and salinity. The measurements were performed by LSC for radium and by spectrophotometry for uranium and europium, using Arsenazo-III. According to the experimental results the maximum chemical recovery of the MnO2-resin for Ra(II) is observed in the pH range between 5 and 7 and selective separation of Ra(II) from aqueous solutions can be triggered by adjusting solution pH and salinity.
