โฆ Synopsis
2-Mercapto-N-2naphthylacetamide
(thionalide) loaded on glass beads with the aid of collodion is used for preconcentration of microgram levels of antimony(II1) from aqueous solution. Antimony is quantitatively retained on the loaded beads from 0.4-0.8 mol 1-l hydrochloric acid solutions; equilibration is achieved within 1 min. The retention capacity of the beads is 0.2 pmol Sb g-' at 0.6 mol 1-l hydrochloric acid. The maximum flow rate for quantitative retention is 1.27 ml min-' cm". Antimony retained on the column is completely eluted with 10 ml of 6.0 mol 1-l hydrochloric acid at flow rates <1.9 ml min-' cm".
