    Abstract:
    This paper studies interference factors in the analysis of mineral elements in salt by FAAS and discusses the problems of background interference, Cl- interference, Na+ interference and other ion interferences. K, Na, Mg, Cu, Mn, Zn, Fe, Pb, Cr and Cd in commercial salt were determined. The results showed that this method did not suit Cr,background absorption only interfered with the determination of K, and Mg, 1% Cl- interfered with the determination of K, and 10% Cl- or 2% Na+ interfered with the other elements. After technical treatment and eliminating all sorts of interferences, the results of analysis for salt are satisfactory.
