摘要: In this paper, a facile immobilization of copper hexacyanoferrate nanoparticles (CuHCFNP) on paraffin wax-impregnated graphite electrode (PIGE) was carried out using the room-temperature ionic liquid (RTIL) 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF4) as an binder. The characteristics CuHCFNP/EMIMBF4 gel-modified were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques, modified morphology also characterized field emission scanning electron microscopy (FESEM). electrocatalytic behavior butylated hydroxyl anisole (BHA) at has been in 0.1 M KNO3 static dynamic conditions. Under optimum conditions, oxidation peak current proportional to BHA concentration range from 1.5 1000 μM with detection limit 0.5 (S/N = 3). proposed method applied determine content real samples satisfactory results.
