Calcium-strontium separation by means of mixed solvent anion exchange

The separation of strontium and yttrium from calcium on the anion exchanger column with alcohol solution of nitric acid as eluent may be described by Glueckauf's model of elution chromatography. Experimental and theoretical results have shown that this separation is characterized by a small number of theoretical plates of the separation column. This model may also be applied for the simulation of the separation of strontium and yttrium from calcium in the strontium isolation from natural samples. The model parameters may be used for the assessment of the optimum column dimension and the optimum working conditions for the isolation of radioactive strontium and yttrium from natural samples.
