Özet
In this study, when Te (IV) and Te (VI) solutions were prepared by deionized water, unexpected differences in the flame AAS sensitivity for Te were found, depending on the oxidation state. Te (IV) gave a significantly greater absorbance than the same concentration of Te (VI) in the air-acetylene flame. However, when these solutions were prepared in 1.0 % (v/v) HNO(3), they had equal sensitivity for flame AAS. This behavior allows one to determine total Te without any error.
