摘要
本文就库仑滴定终点判定问题提出了一种新的硬件终点判定方法——一阶微分峰值自动跟踪法。文中论述了该方法的原理、实现方案与电路,并进行了误差分析的实验研究。结果表明,用此法判定终点可靠性高,误差小,通用性强,具有一定的实用价值。
A new method for end point detecting for coulometric titration is presented called defferential peak tracing automatically. The principle, realization and electronic circuit of the method are discussed. The error analysic and experimental results have been discussed. The result shows the advantages of this method with high reliability, small error and wide applicability.
