| Abstract: | The effect of werking conditions on interference has been studied during the deterthena-tion of Mg in human hair by atoAnc absorption spectrometry. The samples are digested with HNO3-HClO4. When Burner height is 12 mm and the nowrate of C2H2 is 1. 0L/min, Mg can be deterndned directly without any releaser. The recovery ratio is 96%~105%, the relative standard derivation is 3. 0%. |
