In this paper, a simple and sensitive spectrophotometric method for the determination of nanomolar level of bromate, based on the catalytic effect of silver nanoparticles on the oxidation of acid red 14 by potassium bromate, is described. The reaction rate was monitored spectrophotometrically by measuring the decrease in absorbance of acid red 14 at 516 nm. The detection limit of the method was 8 ng/mL, and the linear range was between 15 and 130 ng/mL. The effects of acidity, concentration of…

Determination of bromate via the chemiluminescence generated in the sulfite and carbon quantum dot system
TLDR
The assay is sensitive and represents a new tool for the determination of bromate, which is a carcinogen, and a possible CL mechanism is suggested that involves a redox reaction between the CQDs, bromates and sulfite in the acidic medium.

Flow-injection spectrophotometric determination of bromate in bottled drinking water samples using chlorpromazine reagent and a liquid waveguide capillary cell.
TLDR
In this work, a liquid waveguide capillary cell (LWCC) was coupled to a FIA system to develop a simple, inexpensive method for the determination of low bromate levels in water samples, and the long optical path of the LWCC was used to improve the sensitivity and the limit of detection.
