In this paper, a new method for the determination of trace lead in metallic copper by the sensitometric effect derivative flame atomic absorption spectrometry is proposed. The effect of matrix copper on lead sensitization was studied. The combination of derivative technique and sensitization effect can increase the flame atomic absorption spectrometry sensitivity by 17 times. The determination of trace amounts of copper in metallic copper achieved satisfactory results
