✦ Synopsis

Hydrated antimony pentoxide is used to remove sodium ion for the determination of trace metals in scallop specimens of Plactopecten magellanicus. The concentrations of Cd, Cr, Co, Cu, Au, Fe, Pb, Mn, Hg, Ni, Ag and Zn were determined m the samples and in a standard reference material. Thus method yields improved detection limits with simple apparatus.

## An on-line column preconcentration technique for flow-injection flame atomic absorption spectrometry has been developed for the determination of trace metals in natural waters. A minicolumn (20 mm X 2 mm id.) filled with a poly(aminophosphonic acid) chelating resin (PAPhA, 20-30 mesh) was used
