Description

Electrochemical methods are a broad class of analytical and industrial techniques that involve the interplay of electrical and chemical phenomena. These methods utilize electrochemical cells to measure or induce chemical reactions through the application of electric currents or potentials. The field of electrochemistry plays a pivotal role in energy storage, environmental monitoring, biomedical applications, and industrial manufacturing processes. This article provides an in-depth exploration of electrochemical methods, including their principles, types, applications, and recent advancements. Electrochemical methods rely on the fundamental principles of redox reactions, where electron transfer occurs between chemical species. The core components of electrochemical systems include. Conductive materials that facilitate electron transfer (e.g., platinum, carbon, gold). A medium containing ion that enables charge transport. The driving force for electron movement between electrodes. The flow of electrons due to redox reactions. Electrochemical techniques can be broadly categorized into potentiometric, amperometry, voltametric, coulometric, and impedance-based methods. Potentiometry measures the electric potential (voltage) of an electrochemical cell without drawing significant current. The most common application is the pH measurement using a glass electrode. Other examples include ion-selective electrodes for detecting specific ions in a solution. Amperometry methods involve measuring the current generated by an electrochemical reaction at a fixed potential. This technique is widely used in biosensors, such as glucose sensors, where an enzymecatalysed reaction produces an electrical signal proportional to the analyte concentration. Voltammetry involves applying a varying potential to an electrode and measuring the resulting current. Several forms of voltammetry exist. A steadily increasing potential is applied, and current is recorded. The potential is swept back and forth to study redox behaviour. Use modulated potential signals to enhance sensitivity. Voltammetry is extensively used in environmental monitoring, drug analysis, and material characterization. Coulometric techniques measure the total charge passed during an electrochemical reaction. This method is highly accurate and is used in applications such as water analysis and trace metal detection. EIS analyses the resistance and capacitance of an electrochemical system by applying small alternating voltage signals over a range of frequencies. It is valuable in battery diagnostics, corrosion studies, and biosensor development. Lithium-ion, sodium-ion, and solid-state batteries rely on electrochemical principles for efficient energy storage. Electrochemical reactions in fuel cells convert chemical energy into electricity, offering a sustainable power source. Electrochemical double-layer capacitors provide rapid chargedischarge cycles for high-power applications. Electrochemical sensors detect pollutants, heavy metals, and gases in air and water. Lead and mercury detection in water bodies. Carbon monoxide and nitrogen oxide sensors in air quality monitoring. Electrochemical biosensors, such as glucose sensors, utilize enzyme-electrode interactions to detect biomolecules. Used in genetic analysis and disease diagnosis. Monitoring dopamine and serotonin levels for neurological research. Electrochemical deposition of metals enhances durability and aesthetics in industries. Electrochemical coatings and inhibitors protect infrastructure from degradation. Green chemistry approaches use electrochemical reactions for organic synthesis.
