Bromate Testing In Water
Presence of bromate in drinking water has come into focus after it was reported in
studies that bromate could be responsible for causing cancers. Bromate ions are
produced in drinking water during the process of ozonation.
In ozonation, ozone gas is used as a safe antimicrobial agent for reducing the load
of bacteria and other microorganisms in drinking water. During the ozonation
process, very few by-products are formed but ozone reacts with trace amounts of
bromine present in water to form bromate ions. Small amounts of bromate ions can
also be formed by a process of photoactivation wherein exposure of water to sunlight
causes liquid or gaseous bromine to react with oxygen and form Bromate in
water.
The Bureau of Indian Standards has recently published the 8th Amendment to the IS
14543:2004, Indian Standard specifications for packaged drinking water (PWD). This
amendment introduces the level of bromate content in drinking water and prescribes
the use of ion exchange liquid chromatographic using ISO Method 15061 2001.
All companies involved in the production of packaged drinking water are required
to get their samples tested for the absence of bromate at defined intervals.
This will help you to comply with the requirements of licensing from the Bureau
of Indian Standards.
Our laboratory has recently purchased the required chromatographic system and
has standardized the method as per the ISO 15061. The method in its form is
applicable for testing not only packaged drinking water but can also be extended
to untreated water, surface waters and even wastewater.
Please feel free to contact our laboratory using the contact form on the right
or call us on +91-8588851888. Our team will be happy to provide you with a
proposal for testing your water samples for bromate.
