摘 要: 火焰原子吸收光谱法在 2 71.90 3nm波长处测定 Fe时 ,Pt对其吸收线产生谱线叠加干扰 ,用岭回归法校正了 Pt2 71.90 4 nm光谱法对 Fe2 71.90 3nm的干扰 ,以 Fe元素空心阴极灯同时测定 Fe、Pt两种元素。 The ridge regression method was used to correct the spectral overlap interference of platinum to iron 271.903nm in FAAS,this allowed platinum and iron to be determined simultaneously by using only the iron hollow-cathode lamp.
