Water quality - Determination of permanganate index (ISO 8467:1993)

The principle of the method specified is heating a sample in a boiling water-bath with a known amount of potassium permanganate und sulfuric acid for a fixed period time (10 min), reducing part of the permanganate by oxidizable material in the sample and determining the consumed permanganate by addition of an excess of oxalate solution, followed by titration with permanganate. Applies to waters having a cloride ion concentration of less than 300 mg/l. Samples having a permanganate index over 10 mg/l should be diluted before analysis. The lower limit of the optimum range of the test is 0,5 mg/l.

Wasserbeschaffenheit - Bestimmung des Permanganat-Index (ISO 8467:1993)

Diese Norm beschreibt ein Verfahren für die Bestimmung des Permanganat-Index inWasser. Es dient in erster Linie der Beurteilung von Wasser für den menschlichen Gebrauch; Trinkwasser, natürliches Mineral-, Quell- und Tafelwasser, sowie Schwimm- und Badebeckenwasser. Es wird angewendet zur Bestimmung des Parameters "Oxidierbarkeit". Das Verfahren ist anwendbar auf Wässer mit einer Chloridkonzentration < 500 mg/l Wasserproben mit einem Permanganat-Index > 10 mg/l sollten vor der Analyse verdünnt werden. Die untereAnwendungsgrenze beträgt, bezogen auf Sauerstoff, 0,5 mg/l.

Qualité de l'eau - Détermination de l'indice de permanganate (ISO 8467:1993)

La présente Norme internationale spécifie une méthode pour la détermination de l'indice de permanganate. Elle est principalement destinée aux eaux pour la consommation humaine et à usage domestique, aux eaux potables, eaux minérales naturelles, eaux de table, eaux de source, ainsi qu'aux eaux de piscine. La méthode est utilisée pour la détermination du paramètre «oxydabilité». Elle est applicable à des eaux ayant une concentration en ion chlorure inférieure à 300 mg/l. Les échantillons ayant un indice de permanganate supérieur à 10 mg/l doivent être dilués avant analyse. La limite inférieure de la gamme optimale de l'essai est de 0,5 mg/l.

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. Esch 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.
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.
International Standard ISO 8467 was prepared by Technical Committee
ISOnC 147, Water quality, Sub-Committee SC 2, Physical, Chemical,
biochemical methods.
This second edition cancels and replaces the first edition
(ISO 8467:1986), of which it constitutes a technical revision.

Introduction
The permanganate index is a conventional measure of the contamination
by organic and oxidizable inorganic matter in a water Sample. lt is primarily
intended for judging the quality of potable water and raw waters, such as
weil and surface waters. More heavily contaminated waters may be ana-
lysed, provided an appropriate pre-dilution step is adopted. The per-
manganate index tan be determined for waters containing less than
500 mg/1 of chloride ion. Reducing compounds such as iron(ll) salts, ni-
trites or hydrogen sulfide may contribute to the permanganate index but
are not classified as impurities.
The permanganate index cannot be considered as a measure of the the-
oretical Oxygen demand or the total content of organic matter. Many or-
ganic compounds are only partially oxidized in this test, as Oxidation is
generally incomplete. Volatile matter that evaporates before the addition
of permanganate is not included.
The method is not recommended for determining organic load in waste
waters; for this purpose the Chemical Oxygen demand should be deter-
mined as described in ISO 6060:1989, Water quality - Determination of
the Chemical Oxygen demand.
The method is simple and convenient for suweying the quality of a large
number of water samples.
