| description | The aim of this work was to develop an experimental design to optimize the direct determination of copper in gasoline by graphite furnace atomic absorption spectrometry. The optimization of the process was carried out firstly by evaluating the variables in the procedure (pyrolysis time and temperature, atomization temperature and sample volume) using a factorial design (2
4). The response surface was constructed and it presented pyrolysis optimal temperature on 800 °C, sample volume of 30 μL using the atomization temperature of 2500 °C. The amount of copper in the gasoline samples from São Luis City (Brazil) varied from 3.65 to 16.21 μg L
