【摘要】 建立了高纯钯中16种痕量杂质的电感耦合等离子体质谱测定方法。考察了基体 Pd 的谱干扰和基体效应,采用 Sc、Cs 双内标补偿基体对待测信号的抑制。方法检出限为0.002μg/L～0.04μg/L,加标回收率为86%～114%,分析精密度为0.6%～3.9%。方法简便、快速、灵敏、准确。更多还原

【Abstract】 The method of inductively coupled plasma-mass spectrometry for the determination of impurities of 16 trace elements in highly pure palladium was studied.The spectral interference and matrix effect for palladinm on the method were discussed.The matrix suppression effect of palladinm on signal could effectively be eliminated by using Sc,Cs as internal standard.The determination limit is 0.002μg/L～0.04μg/L,the recovery rate of standand addition is 86 %～114 %,precision is 0.6 %～3.9 %.This method is simple,rapid,sensitive and accurate.更多还原
