一、概述库仑分析法的基础是法拉第电解定律。库仑分析法有恒电位法(即控制电位法)和恒电流法两种。本文仅介绍我们研制的一种恒电位库仑计。早期的恒电位库仑计只是一种用十分简单的手控电路和电位差计构成的装置,操作麻烦,分析时间长,精度低。为了简化分析手续,提高分析速度和精度,Boomen 首先采用运算放大器制成控制电位库仑计,获得了良
First, an overview Coulometric analysis is based on Faraday’s law of electrolysis. Coulometric analysis of potentiostatic method (ie control potential method) and constant current method of two. This article describes only one of our developed coulomb potentiometer. Early coulomb constant potentiometer is only a very simple manual circuit and the composition of the potentiometer device, the operation is cumbersome, long analysis time, low accuracy. In order to simplify the analysis procedure and improve the speed and precision of analysis, Boomen first used the operational amplifier to make the control potential coulometer and obtained the good
