Abstract
The purpose of the present study was to introduce a newly designed approach for deter-mination of glutathione using modified carbon paste electrode with ZnFe2O4nanoparticles, ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate) and ethyl-2-(4-ferrocenyl--[1,2,3]triazol-1-yl)acetate (EFTA/ZFO/IL/CPE). According to the results from the electro-chemical experiments, oxidation current of glutathione on the modified electrode surface was incremented and its oxidation potential was decreased compared to bare CPE. A linear response was observed for the electrode at different glutathioneconcentrations (0.2 to 300.0 μM).
