摘要
本文用在线的微机以Lognormal模型函数处理示差脉冲极谱重迭波。讨论了在KBr支持电解质中In(Ⅲ)和Cd(Ⅱ)的示差脉冲极谱重迭峰。当铟和镉的浓度比为5∶1至1∶15时,分峰结果满意。本法简便、可靠,也可以处理具有导数峰形的其它极谱重迭波。
The overlapping waves of the differential pulse polarograph were resolved using lognormal model function with a on-line microcomputer. The resolution of the overlapping waves for In (Ⅲ) and Cd (Ⅱ) in 0.1 mol/L KBr electrolyte has been given. The results proved that the separation of the peak of In (Ⅲ) from the peak of Cd (Ⅱ) on overlapping waves was highly effective at 5∶1 to 1∶15 for [In^(3+)∶[Cd^(2+)]. The method is simple and accurate and can also process the overlapping waves of the other derivative polarographs.
