本文用偏最小二乘法（ＰＬＳ）校正了火焰原子吸收分析中Ｐｄ２４７．６４３ｎｍ对Ｐｂ２４７．６３８ｎｍ的吸收线重叠干扰，对合成样中Ｐｂ和Ｐｄ的测定，结果令人满意，ＰＬＳ法是谱线重叠干扰的有效校正方法。
In this paper, partial least square method (PLS) was used to correct the absorption interference overlap of Pd247.643nm and Pb247.638nm in flame atomic absorption spectrometry. The determination of Pb and Pd in the synthesized samples was satisfactory. Effective method of correcting interference.
