| Abstract | BIOSIS COPYRIGHT: BIOL ABS. A method for the on-line preconcentration and chromatography of trace metals, e.g., Co, Ni, Cu, Zn, Cd and Pb, on N,N,N',N'-tera(2-aminoethyl)ethylenediamine-bonded silica is described. The preconcentrated metals were desorbed with 0.13 M tartrate, which allows direct separation on a cation-exchange chromatographic column. The metals separated were detected by postcolumn reaction with 4-(2-pyridylazo)resorcinol and measuring the absorbances at 500 nm. Linear calibrations graphs were obtained ove the range 1ynthesis and characteristics of the chelated silica are described. The method was applied to the analysis of river and interstitial sediment waters. |
