Abstract

A flow injection flame atomic absorption method for palladium and platinum determination in solution, including sorption preconcentration, has been developed. Preconcentration of platinum metals as ionic associates with n-octyldiethylenetriamine was carried out on 'reversed phase' styrene-divinylbenzene copolymer SSPS. RSD 0.03-0.08, detection limits 5 and 3 µg l-1 (Pd and Pt) for 1 min of preconcentration and sampling frequency up to 40 h-1 were achieved.
