Volume 10, Issue 1 , March 2023, , Pages 33-42

https://doi.org/10.30473/ijac.2023.67089.1261

Abstract
  In this study, the surface of the glassy carbon electrode (GCE) is modified with the nanocomposite of graphene oxide (GO)/ ionic liquid (1-Butyl-3-methylimidazolium tetrafluoroborate; [BMIM]BF4). The electrochemical behavior of ascorbic acid (AA) and dopamine (DA) at the surface of the modified glassy ...  Read More

Volume 7, Issue 2 , September 2020, , Pages 85-91

https://doi.org/10.30473/ijac.2021.59570.1204

Abstract
  Herein, the electrooxidation of ascorbic acid and folic acid, as two essential vitamins, on the surface of the carbon ceramic electrode modified by polydopamine and copper (Cu/PDA/CCE) was investigated. Poly dopamine was fabricated by applying electro deposition conditions. Initial electrochemical characteristics ...  Read More

Development of An Optical Sensor Based on Sol-gel Doped with 2,6-Dichlorophenol Indophenol for Analysis of Ascorbic Acid

Ashraf Salmanipour; Sara Hooshmand

Volume 1, Issue 1 , March 2014, , Pages 1-6

Abstract
  In this work, an optical sensor for detection of ascorbic acid is described. The sensor is fabricated by casting and spin-coating silica sol-gel doped with 2,6-dichlorophenol indophenol on the glass plates. The sols are in turn obtained by acidic hydrolysis of various precursors such as tetraethoxysilane, ...  Read More
