EN ISO 17380:2013

Soil quality - Determination of total cyanide and easily liberatable cyanide - Continuous-flow analysis method (ISO 17380:2013)

ISO 17380:2013 specifies a method for the photometric determination of the total cyanide and easily-liberatable cyanide content in soil using automated distillation/continuous-flow analysis.
ISO 17380:2013 applies to all types of soil with cyanide contents above 1 mg/kg on the basis of dry matter, expressed as cyanide ion.

Bodenbeschaffenheit - Bestimmung des Gehalts an Gesamtcyanid und leicht freisetzbarem Cyanid - Verfahren mittels kontinuierlicher Durchflussanalyse (ISO 17380:2013)

Diese Internationale Norm legt ein Verfahren fest für die photometrische Bestimmung des Massenanteils an Gesamtcyanid und leicht freisetzbarem Cyanid im Boden unter Anwendung der automatisierten kontinuierlichen Destillations-Durchflussanalyse.
Diese Internationale Norm ist auf alle Bodenarten anwendbar, die einen Cyanidmassenanteil über 1 mg/kg, bezogen auf die Trockenmasse, ausgedrückt als Cyanidion, aufweisen.
ANMERKUNG   Sulfidkonzentrationen in der Probe größer als 40 mg/kg Trockenmasse verursachen Störungen. Dieser Effekt zeigt sich in gespaltenen Peaks und einem langsamen Abnehmen des Detektorsignals und kann nur durch Verdünnen des Probenextrakts verhindert werden.

Qualité du sol - Détermination des cyanures totaux et des cyanures aisément libérables - Méthode d'analyse en flux continu (ISO 17380:2013)

L'ISO 17380:2013 définit une méthode de dosage photométrique de la concentration en cyanures totaux et en cyanures aisément libérables dans le sol par analyse en flux continu et distillation automatisée.
L'ISO 17380:2013 s'applique à tous les types de sols dont la concentration en cyanures, exprimée en ions cyanure, est supérieure à 1 mg/kg de matière sèche.

Kakovost tal - Določevanje celotnega cianida in lahko sprostljivega cianida - Metoda kontinuirane pretočne analize (ISO 17380:2013)

Ta mednarodni standard določa metodo za fotometrično določevanje vsebnosti celotnega cianida in lahko sprostljivega cianida v tleh s samodejno destilacijsko/kontinuirano pretočno analizo. Mednarodni standard se uporablja za vse vrste tal z vsebnostjo cianida, večjo od 1 mg/kg na podlagi suhe snovi, ki je izražena s cianidnim ionom.

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 17380 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical
methods and soil characteristics.
This second edition cancels and replaces the first edition (ISO 17380:2004), which has been
technically revised.

Introduction
Cyanides may be present in soil as cyanide ions and as complex cyanides. They can be determined as
easily-liberatable cyanide or as total cyanide. Complex cyanide can be calculated by subtracting the
easily-liberatable cyanide result from the total cyanide result. This International Standard specifies the
determination of easily-liberatable cyanide, complex cyanides and total cyanide.
Methods using flow analysis automate wet chemical procedures and are particularly suitable for the
processing of many analytes in water or soil extracts in large sample series at a high analysis frequency.
The continuous flow analysis (CFA) method uses an automated dosage of the sample into a flow system
(manifold) where the analytes in th
