Stärke und Stärkederivate - Schwermetallgehalt - Teil 3: Bestimmung des Bleigehaltes durch Atomabsorptionsspektrometrie mit elektrothermischer Atomisierung

Dieser Teil von ISO 11212 legt ein Verfahren für die Bestimmung des Bleigehaltes von Stärke, einschließlich von Derivaten und Nebenprodukten, druch Atomabsorptionsspektrometrie mit elektrothermischer Atomisierung fest. Die die elektrothermische Atomisierung umfassende Anzahl der Parameter des Verfahrens ist weit größer als bei der Flammenatomisierung; es ist folglich ermöglich, ein umfassendes Verfahren vorzuschlagen, das das Erreichen von zufriedenstellenden Ergebnissen für alle gegenwärtig verfügbaren Gerätetypen sicherstellt.

Amidons, fécules et produits dérivés - Teneur en métaux lourds - Partie 3: Détermination de la teneur en plomb par spectrométrie d'absorption atomique avec atomisation électrothermique (ISO 11212-3:1997)

La présente partie de l'ISO 11212 prescrit une méthode pour la détermination de la teneur en plomb dans les amidons, fécules, produits dérivés et sous-produits d'amidonnerie par spectrométrie d'absorption atomique avec atomisation électrothermique. Le nombre de paramètres opératoires impliqués en atomisation électrothermique étant considérablement plus grand qu'en atomisation dans la flamme, il est donc impossible de proposer une méthode détaillée susceptible de garantir l'obtention de résultats satisfaisants sur tous les types d'appareils actuellement commercialisés. Il convient donc que chaque analyste procède à l'optimisation des conditions d'utilisation de son propre instrument sur la base des recommandations générales ou particulières qui lui sont données.

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 11212-3 was prepared by Technical Committee
I SO/IX 93, Starch (including derivatives and by-products).
IS0 11212 consists of the following parts, under the general title Starch
and derived products - Heavy metals content
- Par? 1: Determination of arsenic content by atomic absorption
spectrometry
- Part 2: Determination of mercury content by atomic absorption
spectrometry
- Part 3: Determination of lead content by atomic absorption
spectrometry with electrothermal atomization
- Part 4: Determination of cadmium content by atomic absorption
spectrometry with electrothermal atomization

1 Scope
This part of IS0 11212 specifies a method for the determination of the lead content of starch, including derivatives
and by-products, by atomic absorption spectrometry with electrothermal atomization.
The number of parameters for the procedure involved in the electrothermal atomization is far larger than in flame
atomization; it is thus impossible to propose a comprehensive method likely to ensure the attainment of satisfactory
results on all types of apparatus currently available. Each analyst should therefore optimize the conditions of use of
his/her own apparatus on the basis of general or particular instructions.
