| 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. |
