| Abstract: | Direct determination of copper, iron and sodium in high-purity alumina was performed by slurry-furnace atomic absorption spectrometry with Smith-Hieftje background correction (S-H-GFAAS). Instrument conditions of GFAAS such as pyrolysis, atomization and hollow cathode lamp current by S-H background correction were optimized, and the optimal experimental conditions were selected. Calibration was performed using aqueous standards method for sample analysis. The accuracy of the proposed method was shown for th... |
