Water quality - Determination of total cyanide and free cyanide using flow analysis (FIA and CFA) - Part 2: Method using continuous flow analysis (CFA) (ISO 14403-2:2012)

ISO 14403-2:2012 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations usually from 2 µg/l to 500 µg/l expressed as cyanide ions in the undiluted sample. The range of application can be changed by varying the operation conditions, e.g. by diluting the original sample or changing the pathlength of the flow cell.
In this method, a suitable mass concentration range from10 µg/l to 100 µg/l is described.
Seawater can be analysed with possible changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of the samples.

Wasserbeschaffenheit - Bestimmung von Gesamtcyanid und freiem Cyanid mittels Fließanalytik (FIA und CFA) - Teil 2: Verfahren der kontinuierlichen Durchflussanalyse (CFA) (ISO 14403-2:2012)

Dieser Teil von ISO 14403 legt Verfahren für die Bestimmung von Cyaniden in verschiedenen Wässern (wie
z. B. Grund-, Trink-, Oberflächen-, Sicker- und Abwasser) mit Cyanid-Konzentrationen von üblicherweise
2 µg/l bis 500 µg/l fest, die als Cyanid-Ionen in der unverdünnten Probe angegeben werden. Der
Einsatzbereich kann durch Änderung der Durchführungsbedingungen angepasst werden, z. B. durch
Verdünnen der ursprünglichen Probe oder Änderung der Weglänge der Durchflussküvette.
Der in diesem Teil von ISO 14403 beschriebene geeignete Massenkonzentrationsbereich beträgt 10 µg/l bis
100 µg/l.
Meerwasser kann nach Anpassung von Reagenz- und Bezugslösungen (Kalibrierlösungen) an den Salzgehalt
der Proben sowie mit möglichen Änderungen in der Empfindlichkeit analysiert werden.

Qualité de l'eau - Dosage des cyanures totaux et des cyanures libres par analyse en flux (FIA et CFA) - Partie 2: Méthode par analyse en flux continu (CFA) (ISO 14403-2:2012)

L'ISO 14403-2:2012 spécifie des méthodes pour le dosage des cyanures présents dans divers types d'eau (tels qu'eau souterraine, eau potable, eau de surface, lixiviat et eau résiduaire) en concentrations généralement comprises entre 2 µg/l et 500 µg/l, exprimées en ions cyanure dans l'échantillon non dilué. La gamme d'application peut être modifiée en faisant varier les conditions opératoires, par exemple en diluant l'échantillon d'origine ou en modifiant la longueur du trajet de la cellule de mesure.
La présente méthode décrit une gamme appropriée de concentrations en masse allant de 10 µg/l à 100 µg/l.
L'eau de mer peut être analysée avec des changements de sensibilité et l'adaptation des réactifs et des solutions d'étalonnage à la salinité des échantillons.

Kakovost vode - Določevanje celotnega in prostega cianida s pretočno analizo (FIA in CFA) - 2. del: Metoda s kontinuirano pretočno analizo (CFA) (ISO 14403-2:2012)

Ta del standarda ISO 14403 opisuje metode za določevanje cianida v različnih vrstah vode (na primer podtalni, pitni, površinski, izcedni in odpadni vodi) z običajnimi koncentracijami cianida od 2 µg/l do 500 µg/l, izraženimi s cianidnimi ioni v nerazredčenem vzorcu. Območje uporabe se lahko spremeni s spreminjanjem operativnih pogojev, npr. z redčenjem izvornega vzorca ali s spremembo dolžine poti pretočne celice. V tej metodi je opisano primerno območje masne koncentracije od 10 μg/l do 100 μg/l. Morska voda se lahko analizira z možnimi spremembami občutljivosti ter prilagajanjem raztopin reagenta in raztopin za kalibracijo slanosti vzorcev.

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 14403-2 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical,
chemical and biochemical methods.
This first edition of ISO 14403-2 cancels and replaces ISO 14403:2002, which has been technically revised.
ISO 14403 consists of the following parts, under the general title Water quality — Determination of total cyanide
and free cyanide using flow analysis (FIA and CFA):
— Part 1: Method using flow injection analysis (FIA)
— Part 2: Method using continuous flow analysis (CFA)

ISO 14403-2:2012(E)
Introduction
Methods using flow analysis automate wet chemical procedures and are particularly suitable for the processing
of many analytes in water in large series of samples at a high frequency of analysis.
Analysis can be performed by flow injection analysis (FIA) or continuous flow analysis (CFA). Both methods
share the feature of an automatic introduction of the sample into a flow system (manifold) in which the analytes
in the sample react with reagent solutions on their way through the manifold. Sample preparation may be
integrated in the manifold. The reaction product is measured in a flow detector (e.g. flow photometer).
See the foreword for a list of parts of this International Standard.
It should be investigated whether and to what extent particular problems require the specification of additional
marginal conditions.
