Scholarcy highlights

  • Potassium bromate, a renowned oxidizing agent, has a huge reputation for being one of the best and least expensive dough improving substances in the baking industry
  • The good electrocatalytic activity of this electrode towards BrO3 − reduction in acidic medium was characterized by the high stability, low limit of detection, good reproducibility, fast response time, wide linear dynamic range and technical simplicity
  • This study further revealed that the presence of Ce3+ on the composite is capable of quenching Br− and BrO− in order to inhibit BrO3 − formation
  • cyclic voltammetry studies revealed that the fabricated electrode has good electrocatalytic activity towards trichloroacetic acid and BrO3 − reduction at pH 6.1 in 0.1 M B-R buffer solution
  • We have summarized the efforts made in electrochemical detection of bromate with high sensitivity and selectivity by modifying the electrode surface with different modifiers
  • Owing to the greater advantages of electrochemical impedance spectroscopy and the extraordinary properties of metal phthalocyanine and carbon quantum dots, more studies on the determination of bromate are expected in the near future based on the usage of EIS with regard to metal phthalocyanine and carbon quantum dots
  • All authors have read and agreed to the published version of the manuscript
