摘　　要：以Ｓｒ（ＮＯ３）２：Ｚｎ：ＮａＦ作混合缓冲剂，经粉末法，交流电弧激发直接光谱法测定萘氧化制苯酐催化剂中Ｓｎ、Ｓｂ、Ｍｏ、Ｖ、Ｐｂ、Ｐ、Ａｌ、Ａｇ、Ｍｎ、Ｍｇ、Ｎｉ、Ｂｉ、Ｃｕ、Ｚｎ、Ｃｏ十五种微量元素，最低测定浓度１×１０（－５）％，变动系数１０％～３０％。The elements (Sn, Sb, Mo, V, Pb, P, Al, Ag, Mn, Mg, Ni, Bi,Cu, Zn, Co) in the catalyst for the preparation of phthalic anhydride from naphthalene were detected by alternatingu current arc direct atomic emission spectroscopy.The mixed buffer(Sr(No_3)_2: Zn: NaF)and powder sample were employed in the analysis process. The minimum detectable concentration of the method is 1×10￣15 %, and the variation coefficient is 10-30%.
