Abstract:
Trace Pb and Cd in environmental water samples were preconcentrted and determined by on-line mini-column field sampling and flow injection-flame atomic absorption spectrometry (FI-FAAS), and the adsorption materials of the column were activated carbon loaded 8-HQ, DDTC and APDC. Satisfactory results of the determination of Pb and Cd in the certified reference materials (trace elements in water GBW 08608) and the South lake water were obtained by using the above method. The detection limit of 10 mL enrichment of Pb and Cd was 1.58 and 0.062 microg x L(-1), respectively, and the relative standard deviation of Pb and Cd was 1.62% and 1.96% respectively.
