Water quality - Determination of alkalinity - Part 2: Determination of carbonate alkalinity (ISO 9963-2:1994)

Specifies a method for the titrimetric determination of carbonate alkalinity in natural and drinking water. The method is intended for samples with a carbonate alkalinity between 0,01 mmol/l and 4 mmol/l. For samples containing higher concentrations of alkalinity, a smaller test portion can be used for analysis.

Wasserbeschaffenheit - Bestimmung der Alkalinität - Teil 2: Bestimmung der Carbonatalkalinität (ISO 9963-2:19954)

Dieser Teil von ISO 9963 legt ein Verfahren zur titrimetrischen Bestimmung der Carbonatalkalinität fest. Durch die Wahl eines höheren pH-Werts für den Endpunkt als bei dem in ISO 9963-1 festgelegten Verfahren, verringert sich der Einfluß anderer Wasserstoffakzeptoren, wie beispielsweise Huminsäuren. Das Verfahren ist für Proben geeignet, deren Carbonatalkalinität zwischen 0,01 mmol/l und 4 mmol/l (gerechnet als H+-Äquivalente) liegt. Bei Proben mit höheren Konzentrationen kann eine kleinere Abnahme zur Analyse verwendet werden.

Qualité de l'eau - Détermination de l'alcalinité - Partie 2: Détermination de l'alcalinité carbonate (ISO 9663-2:1994)

La présente partie de l'ISO 9963 prescrit une méthode pour la détermination titrimétrique de l'alcalinité carbonate des eaux naturelles et des eaux potables. En utilisant une valeur de pH plus élevée pour le point de virage que dans la méthode spécifiée dans l'ISO 9963-1, l'influence d'autres prototypes tels que les anions ou les acides humiques est réduite par cette méthode. La méthode est destinée aux échantillons ayant une alcalinité carbonate comprise entre 0,01 mmol/l et 4 mmol/l (en équivalent H+). Pour des échantillons contenant de plus fortes concentrations, une portion d'essai plus faible peut être utilisée. Dans ce contexte, l'alcalinité carbonate est souvent appelée alcalinité totale et possède habituellement la même valeur numérique que celle attribuée à l'alcalinité du méthylorange (alcalinité MO). La détection du point de virage à l'aide d'un pH-mètre est moins sujette aux interférences que l'usage d'un indicateur.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
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 IS0 9963-2 was prepared by Technical Committee
lSO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical,
biochemical methods.
IS0 9963 consists of the following parts, under the general title Water
quality - Determination of alkalinity:
- Part 1: Determination of total and composite alkalinity
- Part 2: Determination of carbonate alkalinity
Annexes A and B of this part of IS0 9963 are for information only.
