摘要： 依据新极谱信号线性迭加原理,采用标准加入法和多元线性回归,提出了新极谱法中重叠峰多元线性回归分辨方法,可以将重叠峰分辨开来,同时可求得产生重叠峰的2个组分的浓度.方法原理简明,计算速度快,具有较高的准确度和极强的分辨能力.应用于In(Ⅲ)-Cd(Ⅱ)和Pb(Ⅱ)一T1(Ⅰ)体系的阶梯扫描新极谱法测定,取得较为满意的结果。

Abstract: A new method for resolution of neopolarographic two-component peaks by multiple linear regression is presented. The method is based on the linear superposition of neopolarograms. The overlapping waves of two species can be resolved and the concentrations of them can be determined by the standard addition and the multiple linear regression. The principle of the method is simple. Its program is fast when executed. It is shown that the method possesses an acceptable accuracy and high resolution when the simulated data being handled. The method has been verified futher by the application of the method to staircase sweep neopolarography of In3+/Cd2+and Pb2+/Tl+systems.
