Abstract

Several enhancement models were used to explain the results obtained in the investigation of Al, Ca, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Rb, Sb, Sn, Sr and Zn using flame atomic absorption spectrometry with a pre-mix burner and six different micellar systems: cetyltrimethylammonium bromide, Triton X-100, ammonium dodecyl sulphate, lithium dodecyl sulphate, sodium dodecyl sulphate and potassium dodecyl sulphate. Similarly, 19 metal cations were used in an interference study with sodium dodecyl sulphate.
