voltammetriaan

Voltammetry is a class of electrochemical techniques in which the potential of an electrode is varied systematically with time, and the resulting current is measured. The applied potential controls the electrochemical reactions occurring at the electrode surface, and the measured current is proportional to the rate of these reactions. By analyzing the relationship between the applied potential and the measured current, information about the identity, concentration, and kinetics of electroactive species in a solution can be obtained.

There are several variations of voltammetry, distinguished by the waveform of the applied potential. Cyclic voltammetry is one of the most common, employing a triangular waveform that sweeps the potential back and forth. Linear sweep voltammetry uses a single sweep in one direction. Differential pulse voltammetry applies small potential pulses superimposed on a linearly increasing potential. Square wave voltammetry uses square-wave potential pulses. These techniques provide distinct advantages for different analytical problems. Voltammetry is a versatile tool used in fields such as analytical chemistry, environmental monitoring, and materials science.
