i_f～E交流示波极谱法的研究

Oscillopolarogram Based on i_f～Curve

本文提出了一种扣除交流示波极谱中充电电流的方法,设计了用微型计算机控制有关仪器的线路。测定了T1^+、In^(3+)、Cd^(2+)、pb^(2+)、Zn^(2+)等离子的法拉第电流和去极剂浓度的关系曲线,提高了交流示波极谱的灵敏度。

This paper presents a method in which charging current is taken off from AC oscillopolaro-graphy. Some Instrumental devices controlled by micro computer were designed. With these devices we determined the i1~E and ip^C curves of T1+, In3+, Cd2+, Pb2+, Zn2+ ions. Where if is the faradic current, ip is the peak current and C is the concentration of depolarizer. The determining sensitivity of AC oscillopolarography was improved.
