Polarography

Introduction Polarography is an electroanalytical technique based on measuring the current-voltage (I-V) relationship in an electrolytic cell with a dropping mercury electrode (DME) or other working electrodes. Polarography was introduced by Jaroslav Heyrovský in 1922, earning him the Nobel Prize in 1959. Principle of Polarography Ilkovic Equation The Ilkovic equation expresses the diffusion current (idi_d) … Read more

Electrochemical Cell

Introduction An electrochemical cell is a device that generates electrical energy from chemical reactions or uses electrical energy to drive chemical reactions. These cells are fundamental in electrochemistry and have various applications in energy storage, corrosion studies, electroplating, and industrial processes. Electrochemical cells operate based on redox (oxidation-reduction) reactions, where electrons are transferred between chemical … Read more
