| Abstract: | Flow injection preconcentration system was introduced into graphite furnace atomic absorption spectrometry in this study. Strongly basic anion exchange fiber was selected as the absorption material, concentrated HCl as complex agent, diluted HCl as eluant. Volume-based elution technique was proposed and applied in this study. Cd, Fe and Zn were determined by the proposed method. The enrichment factors are 19, 17 and 15 (compared with 40 μLsample), the detection limits for the Cd, Pb and Zn are 1.1, 8.2 and 2.6 ng/L, respectively. |
