Abstract
A chelating sorbent obtained by immobilization of thionalide on the ma croporous resin Bio Beads SM-7 was used for speciation of antimony(III ) and (V) in natural waters. Antimony(III) was separated from Sb(V) by sorption on a column with tile sorbent al pH 5. Antimony(V) in the ef fluent was reduced to Sb(III) and preconcentrated by sorption on the s orbent from 0.5M HCl solution. Both the separated species were determi ned directly on the sorbent by neutron activation analysis.
