Dieses Dokument legt ein Verfahren zur Bestimmung der gelösten Anionen Chlorat, Chlorid und Chlorit in wenig belasteten Wässern (z. B. Trinkwasser, Rohwasser oder Badewasser) fest.
Wegen der Vielfalt der in Betracht kommenden geeigneten Gerätekomponenten und der davon abhängenden notwendigen Verfahrensschritte können diese nur in allgemeiner Form beschrieben werden.
Weitere Angaben zu dieser Analysentechnik siehe Literaturhinweise.
Durch entsprechende Probenvorbehandlung (z. B. Verdünnung) sind bei Einsatz eines Leitfähigkeits-detektors (LF), eines UV-Detektors (UV) oder eines amperometrischen Detektors (AD) die Arbeitsbereiche nach Tabelle 1 zu erzielen.

Kakovost vode - Določevanje raztopljenih anionov z ionsko tekočinsko kromatografijo - 4. del: Določevanje klorata, klorida in klorita v malo onesnaženih vodah (ISO 10304-4:2022)
Ta dokument določa metodo za določevanje raztopljenih anionov klorata, klorida in klorita v malo onesnaženih vodah (npr. pitna, neobdelana ali bazenska voda). Zaradi raznolikosti ustreznih in primernih sestavov in od njih odvisnih postopkovnih korakov je mogoče podati le splošen opis. Za več informacij o analizni tehniki glejte poglavje Literatura. Delovni razponi iz tabele 1 so izvedljivi pri ustrezni predhodni obdelavi vzorca (npr. redčenju) in uporabi detektorja prevodnosti (CD), UV-detektorja (UV) ali amperometričnega detektorja (AD).

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee
SC 2, Physical, chemical and biochemical methods, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 230, Water analysis, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 10304-4:1997), which has been
technically revised. The main changes compared to the previous edition are as follows:
— in the introduction, all requirements concerning the application of the method have been deleted
and moved to other clauses;
— in Clause 2, all the references made but withdrawn since the publication of the 1997 edition (e.g.
ISO 10304-2) have been deleted and the references ISO 5667-1 and ISO 5667-3 have been moved to
the Bibliography;
— in 6.8, various eluent formulations have been reduced to one example;
— in Clause 8, the calculation procedure for the peak resolution according to the USP definition
[Formula (1)] has been completed with the EP definition [Formula (2)] (both calculations are
equivalent);
— in 9.1, information that drinking water disinfection treatment using chlorine dioxide can cause the
formation of chlorite and chlorate (paragraph 2) and helpful precautions to minimize/eliminate
such formation (paragraph 3) have been added
