چکیده
|
A square wave voltammetric sensor based on carbon paste electrode modified with cdo nanoparticles (cdo/nps) and 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid (cdo/nps/bihf/cpe) was fabricated for tert-butylhydroxyanisole (bhi) analysis. cdo/nps were characterized with tem and xrd methods. the cdo/nps/bihf/cpe showed good electrocatalytic activity to the electro-oxidation of bhi. the peak currents of square wave voltammograms (swv) of bhi increased linearly with its concentration in the ranges of 0.08–550 μm. the detection limit for bhi was 0.04 μm. the cdo/nps/bihf/cpe was successfully applied for the determination of bhi in food samples. © 2016 by cee (center of excellence in electrochemistry).
