Abstract
Electrochemical sensors are becoming vital and an integral part in our everyday life. Many of the application are biomedical and biochemical. Most popular, and the most expressive, electrochemical sensor is the self-regulation blood glucose meter assist in controlling Diabetes. The other application of electrochemical sensor includes gas sensor which is used in homes to detect CO, metal sensor for water quality Analysis. The electrochemical sensors have also been used in Medical Diagnostic, Food monitoring. This Project confers design and modelling of electrochemical sensor for determining Zn ion in Potassium Hydroxide solution. This model consists of three electrodes reference electrode working electrode counter electrode. In this model electrolyte is taken as Potassium Hydroxide (KOH) which is liquid binary electrolyte and analyte is taken as the zinc [Liquid, tested at 450C (723K)] and carbon material is taken as electrode. The Zinc substance is taken 50mmol/m^3 in the Potassium Hydroxide solution. The main reaction takes place at the working electrode applying potential 0.5V at the working electrode will get the peak current which is proportional to the Zn substance Concentration. Electroanalysis physics is used in COMSOL for the simulation of this project.
