Abstract: The effects of sodium chloride, Sodium dodecyl sulfate, and disodium ethylene diamine tetra acidic acid salts on the absorbance signal of cadmium element using flame atomic absorption spectroscopy (FAAS) were investigated. The absorbance signals were obtained for the analyte and the analyte in the matrix. The comparison of the obtained data with the thermochemical and physical properties of the matrix and the analyte led to conclusions about the interference mechanisms that affect the sensitivity, selectivity, and resolution of the analyte.
