Description
The mixture of Sr and Zr was injected into the column. Zirconium was passed through the column using 3 M HNO3, otherwise, strontium was retained on the column with the same matrix. Then the strontium was eluted with 1% acetic acid with 270 microliters of the elution volume. Total flow rate was about 100 PL/min. The recoveries were 91.0% ± 0.7% and 96.1% ± 0.9% for Sr and Zr, respectably. The microextraction chromatography was applied to separate the Sr and Zr mixture using Sr resin. The recoveries of sample were obtained 91% and 96% for Sr and Zr, respectably. Our method used the hundred microliter scaled sample volume, washing and elution solvent volume resulted in reducing the radionuclide waste significantly compared to traditional extraction chromatography
