ICP-AES测定金属钯中的杂质

Determination of Impuries in Pd by ICP-AES

建立了电感耦合等离子体发射光谱 (ICP- AES) ,同时测定金属钯中 Ag、Al、As、Au、Bi、Ca、Co、Cr、Cu、Fe、Ir、Mg、Mn、Mo、Ni、Pb、Pt、Rh、Ru、Sb、Si、Sn、Ti、Zn等杂质含量的方法。方法简便、快速、准确 ,各杂质的测定精密度在 0 .2 5 %— 3.0 %之间 ,检出限在 0 .0 2 0— 0 .0 62 (μg/ g)之间 ,回收率在 85 %— 10 0

The content of Ag、Al、As、Au、Bi、Ca、Co、Cr、Cu、Fe、Ir、Mg、Mn、Mo、Ni、Pb、Pt、Rh、Ru、Sb、Si、Sn、Ti、Zn as impurities in Pd were determined by ICP-AES.The method was simple,quick and accurate.The detection limit is in the range of 0.020—0.062(μg/g).The RSD is in the range of 0.25%—3.0%.The recovery is in the range of 85%—100%.
