dc.description.abstract
According to the recently rumors about abusing of sodium dithionite (SDT) in baking bread bysome bakers, we motivated to plan a study to fabricate an electrochemical SDT sensor. Thiswork reports our results on fabricating a novel and high performance electrochemical sensorbased on AuPd nanoparticles (AuPd NPs)/chitin-ionic liquid (Ch-IL)/ferrocene dicarboxylicacid-carbon black-ionic liquid (FDCA-CB-IL)/glassy carbon electrode (GCE) to ultrasensitivedetermination of SDT in bread samples. The modifications steps were characterized with thehelp of cyclic voltammetry, electrochemical impedance spectroscopy and scanning electronmicroscopy. After characterization of the modifications, the sensor was electroanalyticallycharacterized by chronoamperometry and the sensor was able to detect SDT in two linear rangesof 0.001-6 and 6-200 μM with a limit of detection of 0.1 nM and a sensitivity of 21.76 μA μM-1.After confirming the capability of the sensor for SDT determination in synthetic samples, it wasapplied to determination of SDT in three Iranian traditional bread samples and fortunately, therewasn?t any SDT in the tested bread samples and to further investigation of the ability of the
