Column chromatographic technique has been utilized to study the column performance of uranyl ion separation on tin(IV) antimonite
hydrous oxide matrix. Different flow rates were applied, at 0.6 ionic strength and pH 3, to evaluate the effect of different
flow rate on column breakthrough behaviour. Van Demeeter equation was used to emphasize the optimum column conditions. High
equivalent to theoretical plate, breakthrough capacity (Q0.5) were also calculated.
