[Determination of trace lead in copper by enhancing effect FAAS-using derivative technique].
A new method for the determination of trace lead in copper is proposed by enhancing effect-flame atomic absorption spectrometry using derivative technique. Enhancing effect of matrix Cu on lead was investigated. The sensitivity for lead was enhanced 17 times than that of conventional flame atomic absorption spectrometry by combining derivative technique with matrix Cu enhancing effect. Determination result is satisfactory by this method with 0.007 microg/mL detection limit and 0.7% RSD.
