Wire Electrode

The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and electrodes. Non-uniform current density distributions can be detrimental for the operation of electrochemical ...

Desalination in an Electrodialysis Cell

Electrodialysis is a separation process for electrolytes based on the use of electric fields and ion selective membranes. Some common applications of the electrodialysis process are: - Desalination of process streams, effluents, and drinking water - pH regulation in order to remove acids from, for example, fruit juices and wines - Electrowinning of precious metals This tutorial demonstrates ...

Glucose Sensor

Electrochemical glucose sensors use amperometric methods to measure the concentration of glucose in a sample. This example models the diffusion of glucose and ferri/ferrocyanide redox mediators in a unit cell of electrolyte above an interdigitated electrode. The sensor gives a linear response over a suitable range of concentrations. The Electroanalysis interface is used to couple the chemical ...

Current Distribution in a Chlor-Alkali Membrane Cell

The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the production of poly vinyl chloride (PVC). Current density in membrane-cell technology has increased ...

Electrochemical Treatment of Tumors

This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the permanent destruction of haemoglobin in the tissue, resulting in the eradication of tumor tissue. This model ...
