Scheme of the (A) oxidative bromination of PR. Spectral changes induced by the oxidative bromination of PR with time for the determination of the haloperoxidase activity of CeO2 obtained (B) from batch chemistry and (C) under segmented flow conditions after annealing at 185 °C, (D) the corresponding absorbance change at 590 nm as a function of time (E) the corresponding absorbance change. Assay components: CeO2 catalyst (25 µg/mL), H2O2 (300 µM), PR.
