单词 | coulostatic analysis |
释义 | coulostatic analysis [´kü·lǝ`stad·ik ǝ`nal·ǝ·sǝs] PHYSICAL CHEMISTRY An electrochemical technique involving the application of a very short, large pulse of current to the electrode; the pulse charges the capacitive electrode-solution interface to a new potential, then the circuit is opened, and the return of the working electrode potential to its initial value is monitored; the current necessary to discharge the electrode interface comes from the electrolysis of electroactive species in solution; the change in electrode potential versus time results in a plot, the shape of which is proportional to concentration. |
