摘　　要：建立了微波消解—电感耦合等离子体原子发射光谱法测定选择加氢催化剂中钯元素的分析方法。系统考察了电感耦合等离子体原子发射光谱法的工作参数,采用标准曲线法和基体匹配法分别定量分析选择加氢催化剂中钯元素。结果表明:铝基体对钯含量的测定有正干扰;基体匹配法可消除干扰,用于选择加氢催化剂的生产控制。A method for the determination of Pd in selective hydrogenation catalyst by ICP-OES has been established.The working parameters of inductively coupled plasma atomic emission spectrometry were systematically investigated and Pd elements in hydrogenation catalysts were quantitatively selected by standard curve method and matrix matching method.The results show that an aluminum matrix has positive interference on the determination of palladium content.Matrix matching method can eliminate the interference and be used in the quality control of selective hydrogenation catalyst.
