Abstract
A method is described for antimony preconcentration based on retention on a column of activated alumina. Recovery is 80% when no pH-control and 4 mol/I HCl as eluent are used. The preconcentration factor is 400 . The method was applied to the determination of antimony in spiked ta p and sea water. The analytical performance of the method is discussed .
