50-mm cell
Attention! The measurement is carried out at 550 nm in a 50-mm rectangular cell against a blank, prepared
from distilled water (Water for analysis EMSURE
®
, Cat.No. 116754, is recommended) and the
reagents in an analogous manner.
Bromate in water and
drinking water
Application
Evaporate 200 ml of
sample solution in a
glass beaker almost to
dryness on the hob.
Place the cell into the
cell compartment.
Select method no. 1195.
Filter turbid samples. Transfer the residue to a
20-ml volumetric glass
using a little distilled
water (Water for analysis
EMSURE
®
, Cat.No.
116754, is recommend-
ed).
Pipette 10 ml of the pre-
treated sample into a
test tube.
Add 0.10 ml of
reagent 1 with pipette
and mix.
Add 0.20 ml of
reagent 2 with pipette
and mix.
Add 0.20 ml perchloric
acid 70 - 72 % GR
(Cat.No. 100519) with
pipette and mix.
Reaction time:
30 minutes
Transfer the solution into
a cell.
Important:
The exact composition and preparation of the reagents 1
and 2 used are given in the corresponding application,
which also includes further inf
ormation on the method
employed. This application can be downloaded directly at

Make up the contents of
the volumetric flask to
the mark with distilled
water
(Water for analysis
