Abstract

Electrothermal atomic absorption spectrometer with spiral tungsten filaments as platform for determination of antimony

Author(s): Mahmood Salman

The Electrothermal Atomic Absorption Spectrophotometer (ETAAS) is one of the most important analytical techniques in the field of elemental determination owing to its high sensitivity. The best results were achieved by using spiral tungsten filaments-ETAAS. The new method approved by using certified standard IAEA. Certified standard reference materials were analyzed for the assessment of accuracy of proposed method. Calibration plots for Antimony in both methods were achieved. The calibration plot was liner from 20 to 120 ppb for the spiral tungsten filaments-ETAAS. Correlation coefficients found were at least 0.998 for direct calibration and the recovery was 102%.
