28、al 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 e
29、stablished 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 standard
30、ization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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
31、75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15061 was prepared
32、 by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical and biochemical methods. Annexes A, B, C, D and E of this International Standard are for information only.

33、irements of an ion chromatographic system applied within the scope of this International Standard for the determination of dissolved bromate are given in clause 5. The diversity of the appropriate and suitable assemblies, and the procedural steps depending on them, permit a general description only.

35、ography of ions 1 Scope This International Standard specifies a method for the determination of dissolved bromate in water (e.g. drinking water, raw water, surface water, partially treated water or swimming pool water). Appropriate pretreatment of the sample, for example by elimination of chloride,
36、sulfate, metals, preconcentration or dilution, gives a range of applicability of 0,5 g/l to 1 000 g/l dissolved bromate. The working range is restricted by the ion-exchange capacity of any preconcentration columns used and that of the separator column. Dilution of the sample to the working range may
37、 be necessary. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, pa
38、rties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

42、 affect the capacity of the concentrator column and lead to poor recovery of bromate (9.2.1). 3.2 The presence of chloride, sulfate, carbonate and hydrogen carbonate can cause interference with the determination of bromate (9.2.1). Depending on the column utilized, other ions may interfere; this sho
43、uld be checked. 3.3 Metals present (e.g. barium and silver ions released from sample pretreatment steps) will bind to the resin material of concentrator and separator columns, resulting in a loss of performance. Metal ions may be eliminated with the aid of a metal clean-up column or special exchange

45、anic compounds such as mineral oils, detergents and humic acids shorten the life-time of the concentrator and separator column. 4P r i n c i p l e 4.1 Sample pretreatment is carried out in order to remove ozone (9.1.3) and solids, and to reduce chloride, sulfate, carbonate, hydrogen carbonate and me
46、tals present by use of cation exchangers (9.2). 4.2 Measurement of bromate is made in the range 0,5 g/l to 1 000 g/l, with or without preconcentration (10.3). 4.3 Liquid chromatographic separation of bromate is carried out either by means of a separator column or after elution of bromate from a conc
47、entrator column, if used. An anion exchange resin is used as the stationary phase, and usually, aqueous solutions of salts of weak mono- and dibasic acids as eluent (see 6.10 and annex A). 4.4 A conductivity detector (CD) with chemical suppression is used. A UV detector ( = 190 nm to 205 nm) is suit
48、able to confirm the CD results only. NOTE When using conductivity detectors it is essential that the eluents have a sufficiently low conductivity. For this reason, conductivity detectors are combined with a suppressor device (cation exchanger) which reduces the conductivity of the eluent and transforms the sample species into their respective acids. UV detection measures absorbance
