Determination of copper in gasoline by atomic absorption spectrometry with electrothermal atomization

Cu determination in crude oil distillation products by atomic absorption and inductively coupled plasma mass spectrometry after analyte transfer to aqueous solution

“…According to literature data, Cu is usually determined by ETAAS without chemical modification [3,5,[7][8][9]23]. In the case of using the most widely applicable modifiers, palladium and magnesium, spectral interferences should have been taken into account, as the Pd 324.270 nm line is very close to the Cu 324.754 nm analytical line [29].…”

“…Cu, like other heavy metals, is enriched in the heavy fractions and in the residue of distillation, as well as in the deposits on catalysts of the destruction refinery processes. Finally, it is found in sewage sludges, wastes, and the refinery environment (Table 1) [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Among the materials of different origin and destination, the reforming feed, apart from seawater, contains the smallest amount of Cu [1][2][3][4][5][6][7].…”

“…For the determination of Cu in petroleum products, optical and mass spectrometry techniques have been applied, including flame atomic absorption spectrometry (FAAS) [4,21], electrothermal atomic absorption spectrometry (ETAAS) [3,5,[7][8][9][10], inductively coupled plasma mass spectrometry (ICP-MS) [6,11,14], inductively coupled plasma atomic emission spectrometry (ICP-AES) [22], as well as, molecular spectrophotometry [12,13]. Most of the papers were devoted to gasoline analysis [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
