Electroanalytical techniques are thought to be the most significant area of analytical chemistry, which identify the properties as well as quantify the given analyte(s) within an electrochemical cell. The high sensitivity, high analysis speed, low sample and solvent consumption, high scan rate, low operating cost of electro analysis make it highly advantageous in all situations. A summary of electroanalytical techniques is provided, with an emphasis on their most common uses in the identification of distinct analytes. These techniques include cyclic voltammetry (CV), square wave voltammetry (SWV), differential pulse voltammetry (DPV), electrochemical impedance spectroscopy (EIS), and voltammetry in square waves (SWV). This review explains the electrochemical applications of electroanalytical techniques in different fields. CV is widely used for studying the electrochemical properties of molecules, particularly in redox reactions. It provides detailed information about the oxidation and reduction processes of the analytes. SWV offers enhanced sensitivity and is particularly useful in trace analysis of complex matrices. DPV is employed for its high sensitivity and resolution in detecting low concentrations of analytes. EIS is used for characterizing the electrical properties of materials and interfaces, often in the study of corrosion, batteries, and sensor development. The versatility and efficiency of these techniques make them indispensable in environmental monitoring, pharmaceutical analysis, and material science, among other fields.
