Bromate in Water and Drinking Water

Bromate in Water and Drinking Water

25 Jan 2016

Bromate can occur in drinking water treatment in the oxidation of bromide-containing waters with ozone. Bromates are carcinogenic, these substances in drinking water are undesirable and there are limits for drinking water in many countries. The EU drinking water directive prescribes as a maximum allowable concentration of Bromate in drinking water by 0.010 mg/l BrO3- (or 10 μg/l BrO3-). The same limit is also in the WHO guideline for drinking water. Local regulations often prescribe these limit values too. This application note provides an overview of the methods available from MilliporeSigma.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Method DevelopmentMethod development is the process of creating and optimizing experimental techniques and protocols to achieve reliable, reproducible results. This is essential in various fields, including pharmaceuticals, environmental science, and diagnostics.
