“…are an important part of the analytical chemistry [1][2][3][4] because of ecological and health problems associated with environmental contamination continues to rise. Due to the relatively simple and inexpensive equipment required, flame atomic absorption spectrometry (FAAS) is preferred as main instrument for many environmental chemistry laboratories for heavy metal determinations [5][6][7]. However in flame atomic absorption determinations of the heavy metal ions, unfavorable influences of matrix components of real samples and particularly low concentrations of heavy metal ions are two big problems [8][9][10][11].…”
