多波长数据线性回归法在火焰原子吸收同时测定Fe、Pt中的应用
Simultaneous Determination of Iron andPlatinum by FAAS with Multiwavelength Linear Regression
【摘要】 用火焰原子吸收法在271.903nm处测定Fe时,Pt对其吸收线发生谱线重叠干扰,本实验用多波长数据线性回归法理想地校正了Pt271.904nm对Fe的271.903nm干扰,实现了用Fe元素空心阴极灯同进测定Fe、Pt两种元素。
【Abstract】 There is a spectral overlap interferenceof platinum to iron 271.903nm in FAAS.The linear regression method of multiwave-length was used to compensate this spectraIinterference,this allowed platinum and ironto be determined simultaneously by usingonly the iron hollow-cathode lamp
