These data demonstrate that all these factors have statistically significant effects on the analytical signal under the experimental conditions established. The atomization temperature had a positive effect, which was the largest among the four factors. The positive effect indicates that an increase in the atomization temperature contributes to an increase in the absorbance. This relationship can be observed by comparing the absorbances obtained at temperatures of 1300 and 1800 C. The other factors were significant; however, the magnitudes of these effects were considerably smaller than that of the effect of the atomization temperature.
