摘    要:试样用HCl-HNO3溶解,采用多元光谱拟合(MSF)功能ICP-AES法同时测定铂中22个杂质元素:Pd、Rh、Ir、Ru、Au、Ag、Cu、Fe、Zn、Ni、Mn、Cr、Mg、Cd、Al、Ca、Pb、Sn、Bi、Si、Mo、Ti。对基体铂的影响、MSF功能、元素分析谱线、背景校正、仪器分析参数等进行了研究,确定了最佳实验条件。杂质元素测定范围Ag、Pd、Cu、Cr、Ti、Mn和Mo为0.0004%~0.05%;Rh、Ir、Pb、Fe、Mg、Al、Zn、Si、Bi、Ca、Cd、Sn、Au和Ni为0.0005%~0.05%;Ru为0.001%~0.05%;方法的相对标准偏差(RSD)和加标回收率分别为1.5%~8.1%和85.1%~118.5%。方法准确、快速、简便,已用于铂中杂质元素的分析。

关 键 词:分析化学  多元光谱拟合(MSF)  电感耦合等离子体原子发射光谱法    杂质元素

Abstract:A new method of MSF for determination of 22 impurities by ICP-AES has developed.These impurities including Pd,Rh,Ir,Ru,Au,Ag,Cu,Fe,Zn,Ni,Mn,Cr,Mg,Cd,Al,Ca,Pb,Sn,Bi,Si,Mo and Ti in pure platinum.The samples were dissolved in HCl-HNO3 prior to the measurments.The influencing factors,such as interference of platinum,MSF,spectra of analyzed element,background correction and instrument parameters,were investigated.The determination levels are in the range from 0.0004% to 0.05% for Ag,Pd,Cu,Cr,Ti,Mn and Mo,from 0...
Keywords:analytical chemistry  MSF  ICP-AES  platinum  impurities
