|Title:||Fabrication of a Home-made SPCE Modified with Thionine for Determination of Hydrogen Peroxide|
|Publisher:||Science Faculty of Chiang Mai University|
|Abstract:||A disposable screen-printed carbon electrode (SPCE) was fabricated by a simple screen printing method which is widely used for the mass-production of the electrochemical sensor. These home-made SPCEs were modified to apply to the determination of hydrogen peroxide. The conditions of the SPCEs fabrication process were described including curing time, curing temperature, dilution ratio, and a number of repeated printing of carbon ink. The investigation of electrochemical surface pretreatment was then carried out in acidic solution regarding their influence on the electrochemical properties of SPCEs. In addition, the modification of thionine on SPCEs was carried out with electropolymerization to enhance the sensitivity of the electrode. The resulting thionine modified SPCEs was successfully applied to the determination of hydrogen peroxide in the real samples.|
