摘　　要：报道了用ICP AES法测定催化剂洗余液中W、Ni、Na、Zr的含量。研究了正向功率、观测高度、光谱干扰等对测定结果的影响,选择出同时测定Na、Ni和Zr的条件。方法对Na、Ni、Zr的检出限分别为6.5、2.3、8.2μg/mL。The method has been propesed for the determination of W,Ni,Na and Zr in washing liquids of the catalysts.The factors influencing on the ICP discharge were studied and the optimal operating conditions were established. The proposed methed was applied to the determination of W,Ni,Na and Zr with satisfactory results.
