elektroanalüütiliste

elektroanalüütiliste refers to methods and techniques used in electrochemistry for the analysis of chemical substances. These methods rely on the relationship between electrical properties and chemical composition. Essentially, they involve measuring electrical quantities such as potential, current, or charge to determine the concentration or identity of an analyte.

Common electroanalüütiliste techniques include potentiometry, voltammetry, and coulometry. Potentiometry measures the electrical potential difference between two electrodes in a solution, which is directly related to the concentration of specific ions. Voltammetry, on the other hand, involves applying a varying potential to an electrode and measuring the resulting current. This current is proportional to the concentration of electroactive species. Coulometry utilizes the quantitative relationship between the amount of electricity passed and the amount of chemical change produced. By measuring the total charge transferred during an electrochemical reaction, the amount of analyte can be determined.

These techniques are widely used in various fields, including environmental monitoring, pharmaceutical analysis, and industrial process control. Their advantages include high sensitivity, selectivity, and the ability to perform analyses in situ or in real-time. The development of sophisticated instrumentation and electrode materials continues to expand the capabilities and applications of electroanalüütiliste methods.
