Cuir — Détermination des alkylphénols éthoxylés (APEO) — Partie 1: Méthode directe
Le présent document spécifie une méthode de détermination des alkylphénols éthoxylés (APEO) [éthoxylate de nonylphénol (NPEOn, où 2 ≤ n ≤ 16) et éthoxylate d’octylphénol (OPEOn, où 2 ≤ n ≤ 16)] dans le cuir. Cette méthode d’analyse directe convient particulièrement lorsque les alkylphénols éthoxylés doivent être dosés sur un grand nombre d’échantillons de cuir.
L’analyse est effectuée par…
