## 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
Resins synthesized from qumohn-b-01 and resorcmol or hydroqmnone, with furfuraldehyde, formaldehyde or benzaldehyde as cross-hnkmg agent, were used for the preconcentrafion of nanogram amounts of lead The rate of exchange and activation energy of lead exchange were calculated Column separations of l
