Coulometry - Wikipedia
网页In analytical electrochemistry, coulometry determines the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. It can be used for precision measurements of charge, and the amperes even used to have a coulometric definition.

网页2014年1月1日 · During coulometry at constant potential, the total amount of charge (Q) is obtained by integration of the current (I) – time (t) curve or Q can be determined directly by using a coulometer (electronic integrator).
Coulometry - an overview | ScienceDirect Topics
网页In coulometry, the current, created by analyte exhaustive oxidization or reduction, is measured (Harvey, 2000). This technique can be used for the quantitative analysis of various inorganic and organic compounds. There are two types of coulometry: controlled-potential and controlled-current coulometries (Harvey, 2000).
