摘　　要：用电感耦合等离子(ICP)发射光谱法,快速同时测定催化裂化、催化裂解催化剂中的微量铁、镍、铜、钒、钠、锑等金属元素含量,通过谱线选择、分析条件优化等措施有效避免了各种干扰。各元素的相对标准偏差(RSD)分别为铁0.41%、镍0.94%、铜6.36%、钒0.98%、钠0.31%、锑1.21%,加标回收率均大于91%,方法准确可靠。Trace iron, nickel, copper, vanadium, sodium, antimony in catalysts for catalytic pyrolysis and catalytic cracking were determined by ICP. The interferences were effectively avoided through spectral line selection and optimization of conditions. The results show that the relative standard deviations for each element （RSD） are as follows： Fe 0.41%,Ni 0.94%, Cu 6.36%,V 0.98%,Na 0.31%,Sb 1.21%. The recoveries are greater than 91%.This method is accurate and reliable.
