摘要: 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Tl+、In3+、Cd2+、pb2+、Zn2+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。

Abstract: This paper presents a method in which charging current is taken off from ACoscillopolaro-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 ifis the faradic current, ipis the peak current and Cis the concentration of depolarizer. The determining sensitivity of ACoscillopolarography was improved.

Key words: AC oscillopolarography, Faradic current, Computerized oscillopolarographic instrument
