Water quality - Determination of total cyanide and free cyanide using flow analysis (FIA and CFA) - Part 1 : method with flow injection analysis (FIA)

ISO 14403-1:2012 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations 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 using a different injection volume. In ISO 14403-1:2012, a suitable mass concentration range from 20 µg/l to 200 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.

Water quality - Determination of total cyanide and free cyanide by continuous flow analysis

<p> La présente Norme internationale 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 eaux usées) en concentrations généralement supérieures à 3 µg/l, exprimées en ions cyanure. La méthode CFA est applicable à une gamme de concentrations comprises entre 10 µg/l et 100 µg/l. La gamme d'application peut être modifiée en faisant varier les conditions de fonctionnement. <br/> <br/>NOTE 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. </p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
