Cyclic voltammetry คือ

WebSep 4, 2024 · Cyclic voltammetry (CV) is an electrochemical method which measures the current that develops in an electrochemical cell under conditions where voltage is in excess of that predicted by the Nernst equation. CV is performed by cycling the potential of a working electrode, and measuring the resulting current. WebIn cyclic voltammetry, the potential is repeatedly scanned to a certain potential and back. In the potentiostatic technique the potential can be altered step-by-step to gain informations on a potential range of interest. Fig. 18.1 shows schematically a polarization or current density/potential curve of an actively corroding metal such as iron ...
