Voltammetry is an electrochemical technique used to measure the current that flows in a solution as a function of an applied voltage. This method helps analyze the concentration of various chemical species by observing how they react at an electrode surface. It is widely used in fields like analytical chemistry and environmental monitoring. In voltammetry, a potential is applied to an electrode, causing oxidation or reduction reactions of the analytes present in the solution. The resulting current is recorded, providing valuable information about the chemical properties and concentrations of the substances being studied. This technique is essential for detecting trace levels of pollutants and biomolecules.
