Chromatographic studies on the uptake of cobalt and uranium from nitrate solution on Al-13-phosphatoantimonic acid

摘要

Chromatographic extraction of cobalt and uranium from nitrate solution on Al-13-phosphatoantimonic acid and Dowex 50X8 resin at 0.6 ionic strength and pH 2 was studied. Saturation capacity was studied and found to be 0.8 and 0.5 meq/g for Co~(2+) and 1.1 and 0.8 meq/g for UO_2~(2+) ions, using A;-13-phosphatoantimonic acid (Al-13-PAA) and Dowex 50X8, respectively. The effect of flow rate and on the column performance was investigated. Theoretical plate height and Van Deemter equation parameters were also evaluated.
