Water quality - Determination of dissolved bromate - Method using ion chromatography (IC) and post column reaction (PCR) (ISO 11206:2011)
ISO 11206:2011 specifies a method for the determination of dissolved bromate in water (e.g. drinking water, mineral water, raw water, surface water, partially treated water or swimming pool water).
Appropriate pretreatment of the sample (e.g. dilution) allows determination of bromate at concentrations ³0,5 µg/l.
The working range is restricted by the ion‑exchange capacity of the separator column. Dilution of the sample to the bromate working range can be necessary.
Wasserbeschaffenheit - Bestimmung von gelöstem Bromat - Verfahren mittels Ionenchromatographie (IC) und Nachsäulenreaktion (PCR) (ISO 11206:2011)
Diese Internationale Norm legt ein Verfahren zur Bestimmung von gelöstem Bromat in Wasser (z. B. Trinkwasser, Mineralwasser, Rohwasser, Oberflächenwasser, teilweise behandeltes Wasser oder Badewasser) fest.
Eine geeignete Probenvorbehandlung (z. B. Verdünnung) erlaubt die Bestimmung von Bromatkonzentrationen ≥ 0,5 µg/l.
Der Arbeitsbereich ist durch die Kapazität der Trennsäule begrenzt. Eine Probenverdünnung in den Arbeitsbereich kann erforderlich sein.
Qualité de l'eau - Dosage du bromate dissous - Méthode utilisant la chromatographie ionique (IC) et la réaction post-colonne (PCR) (ISO 11206:2011)
L'ISO 11206:2011 spécifie une méthode pour le dosage du bromate dissous dans l'eau (par exemple l'eau potable, l'eau minérale, l'eau brute, les eaux de surface, l'eau partiellement traitée ou l'eau de piscine).
Le prétraitement approprié de l'échantillon (par exemple dilution) permet de doser le bromate à des concentrations supérieures ou égales à 0,5 µg/l.
Le domaine de travail est limité à la capacité d'échange ionique de la colonne de séparation. Il peut être nécessaire de diluer l'échantillon dans le domaine de travail du bromate.
Kakovost vode - Določevanje raztopljenega bromata - Metoda z ionsko kromatografijo in pokolonsko reakcijo (PCR) (ISO 11206:2011)
Ta mednarodni standard določa metodo za določevanje raztopljenega bromata v vodi (npr. pitna, mineralna, surova, površinska, delno pripravljena ali bazenska voda). Ustrezna predpriprava vzorca (npr. redčenje) omogoča določevanje bromata pri koncentraciji 0,5 μg/l. Delovni obseg je omejen z zmogljivostjo ionske izmenjave separatorske kolone. Morda je potrebno redčenje vzorca do delovnega obsega bromata.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11206 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical,
chemical and biochemical methods.

INTERNATIONAL STANDARD ISO 11206:2011(E)
Water quality — Determination of dissolved bromate — Method
using ion chromatography (IC) and post column reaction (PCR)
WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This standard does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted according to this International Standard
be carried out by suitably trained staff.
1 Scope
This International Standard specifies a method for the determination of dissolved bromate in water (e.g. drinking
water, mineral water, raw water, surface water, partially treated water or swimming pool water).
Appropriate pretreatment of the sample (e.g. dilution) allows determination of bromate at concentrations �0,5 µg/l.
The working range is restricted by the ion-exchange capacity of the separator column. Dilution of the sample
to the bromate working range can be necessary.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.
ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 8466-1, Water quality — Calibration and evaluation of analytical methods and estimation of performance
characteristics — Part 1: Statistical evaluation of the linear calibration function
ISO 8466-2, Water quality — Calibration and evaluation of analytical methods and estimation of performance
characteristics — Part 2: Calibration strategy for non-linear second order calibration functions
3 Interferences
Metals present in samples and eluents bind to the resin material of the separator column, resulting in a loss of
performance. Metal ions can be eliminated with the aid of special cation exchangers (see 6.2 and Clause 8, Note 1).
Solid particles and organic compounds (e.g. mineral oils, detergents, and humic acids) shorten the lifetime of
the precolumn and the separator column (see Clause 8, Notes 2 and 3).
Chlorite can interfere with the determination of bromate. Remove chlorite in accordance with the procedure
specified in 9.4, if necessary.
NOTE Any substance that has a retention time coinciding with bromate and that produces a detector response can
interfere. A high concentration of ions can have an impact on the resolution and on the analyte’s retention time. Sample
dilution and/or gradient elution overcomes much interference.
4 Principle
The sample is pretreated in order to remove ozone, chlorine dioxide, chlorite, metals and solids, if necessary
(see Clause 8). Bromate is separated by ion chromatography (IC). An anion exchange resin is used as the
stationary phase and either acids (e.g. sulfuric acid) or aqueous solutions of salts of weak monobasic acids
