Preperation
1. Cleaning of vials:
As many household cleaners (e.g. dishwasher detergent) contain reducing
substances, the subsequent determination of oxidising agents (e.g. ozone and
chlorine) may show lower results. To avoid measurement errors, the glassware
used should be free of chlorine consumption. To achieve this, all glassware should
be placed in a sodium hypochlorite solution (0.1 g/l) for one hour and then rinsed
thoroughly with deionised water.
2. When preparing the sample, Bromine outgassing, e.g. through the pipette or shaking,
must be avoided. The analysis must take place immediately after taking the sample.
3. Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7
before the analysis (use 0.5 mol/l Sulphuric acid or 1 mol/l Sodium hydroxide).
