Bromate monitoring in disinfected water |
|
|
Istran has introduced a new application for on-line bromate measurement
in disinfected water. Concentrations down to few ppb of bromate can be
detected within 15 min.
Some water sources contain bromides and improper water treatment
technology may give rise to highly dangerous bromate. Its concentration
must not exceed 10 ug/l. Such low bromate concentrations can only be
measured by sophisticated chromatographic and isotachophoretic
techniques, which are not suited for on-line and unattended monitoring
of bromates.
Istran has introduced a new application for
on-line bromate measurement in disinfected water by making use of the
user-friendly and low cost process analyzer EcaMon TE10. The method has
recently be tested in a long-term test on water samples with and
without bromate contents. Virtually no interference from disinfection
reagents and their byproducts was observed and the system provided
reliable values for bromate concentrations below as well as above the
10 ppb threshold value. The results corresponded well with those
obtained by HPLC.
The on-line bromate analyser EcaMon TE10. Measuring range 1 to 100 ug/l BrO3-, Response time 14 min.
