Leather - Determination of ethoxylated alkylphenols (APEO) - Part 1: Direct method (ISO 18218-1:2023)

ISO 18218-1:2015 is a method for determining ethoxylated alkylphenols (nonyphenol ethoxylate [NPEOn with 1 ≤ n ≤ 16] and octylphenol ethoxylate [OPEOn with 1 ≤ n ≤ 16]) in leather. This direct method is especially suitable where a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols.
This method requires the use of high-performance liquid chromatography (HPLC) with triple quadrupole mass spectrometer (MSMS) to identify and quantify the ethoxylated alkylphenols.
NOTE 1 In the leather industry, the most commonly used commercial ethoxylated alkylphenol is the NPEO with an average of 9 EO. It has an optimum cloud point in water for the typical leather processing temperatures of 40 °C to 55 °C.
NOTE 2 ISO 18218-1 and ISO 18218-2 use different solvents for the extraction of the ethoxylated alkylphenols from leather. Consequently, the two analytical methods are expected to give similar trends but not necessarily the same absolute result for the ethoxylated alkylphenol content in leather.

Leder - Bestimmung von ethoxylierten Alkylphenolen (APEO) - Teil 1: Direktes Verfahren (ISO 18218-1:2023)

Dieses Dokument legt ein Verfahren zur Bestimmung von ethoxylierten Alkylphenolen (APEO) [Nonylphenolethoxylat (NPEOn, wobei 2 ≤ n ≤ 16) und Octylphenolethoxylat [OPEOn, wobei 2 ≤ n ≤ 16)] in Leder fest. Dieses direkte Verfahren ist besonders geeignet, wenn eine größere Anzahl von Lederproben auf die Anwesenheit von ethoxylierten Alkylphenolen zu überprüfen ist.
Dieses Verfahren erfordert die Anwendung der Flüssigkeitschromatographie (LC) mit einem Triple-Quadrupol-Massenspektrometer (MS/MS), um ethoxylierte Alkylphenole zu identifizieren und quantitativ zu bestimmen.
ANMERKUNG 1   Das in der Lederindustrie am häufigsten verwendete ethoxylierte Alkylphenol ist NPEO mit einem Mittelwert von 9 EO. Es hat bei den typischen Verarbeitungstemperaturen von Leder von 40 °C bis 55 °C einen optimalen Trübungspunkt in Wasser.
ANMERKUNG 2   Dies Dokument und ISO 18218 2 verwenden verschiedene Lösemittel zur Extraktion der ethoxylierten Alkylphenole aus Leder. Für die beiden analytischen Verfahren wird erwartet, dass sie für den Gehalt ethoxylierter Alkylphenole in Leder konsequenterweise ähnliche Tendenzen, jedoch nicht zwangsläufig das absolut identische Ergebnis liefern.

Cuir - Détermination des alkylphénols éthoxylés (APEO) - Partie 1: Méthode directe (ISO 18218-1:2023)

ISO 18218-1:2015 spécifie une méthode de détermination des alkylphénols éthoxylés (éthoxylate de nonylphénol [NPEOn, où 1 ≤ n ≤ 16] et éthoxylate d'octylphénol [OPEOn, où 1 ≤ 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 chromatographie en phase liquide à haute performance (CLHP) couplée à la spectrométrie de masse en tandem avec un analyseur à triple quadripôle, afin d'identifier et de quantifier les alkylphénols éthoxylés.
NOTE 1 Parmi les alkylphénols éthoxylés disponibles dans le commerce, celui qui est le plus utilisé dans l'industrie du cuir est l'éthoxylate de nonylphénol contenant en moyenne 9 groupes éthoxy. La température de trouble dans l'eau de cette substance est optimale compte tenu des températures généralement utilisées pour le traitement du cuir, qui sont comprises entre 40 °C et 55 °C.
NOTE 2 L'ISO 18218‑1 et l'ISO 18218‑2 impliquent l'utilisation de solvants différents pour l'extraction des alkylphénols éthoxylés du cuir. Par conséquent, on peut s'attendre à ce que les résultats obtenus en suivant l'une des deux méthodes analytiques soient comparables à ceux obtenus en suivant la seconde méthode, mais non nécessairement identiques, pour ce qui concerne la teneur en alkylphénols éthoxylés dans le cuir.

Usnje - Določevanje etoksilatnih alkilfenolov - 1. del: Neposredna metoda (ISO 18218-1:2023)

Standard ISO 18218-1:2015 določa metodo za določevanje etoksilatnih alkilfenolov (nonilfenol etoksilatov [NPEOn z 1 ≤ n ≤ 16] in oktilfenol etoksilatov [OPEOn z 1 ≤ n ≤ 16]) v usnju. Ta neposredna metoda je primerna zlasti, če je treba prisotnost etoksilatnih alkilfenolov preveriti pri večjem številu usnjenih vzorcev.
Ta metoda zahteva uporabo tekočinske kromatografije visoke ločljivosti (HPLC) z masnim spektrometrom s trojnim kvadrupolom (MSMS) za identifikacijo bisfenolov in ugotavljanje njihove količine.
OPOMBA 1: Med komercialnimi etoksilatnimi alkilfenoli se v usnjarski industriji najpogosteje uporablja nonilfenol etoksilat, ki v povprečju vsebuje 9 enot etilenoksida (EO). Njegovo motnišče v vodi je optimalno za tipične temperature pri obdelavi usnja, ki znašajo med 40 °C in 55 °C.
OPOMBA 2: v standardih ISO 18218-1 in ISO 18218-2 se uporabljata različni topili za ekstrakcijo etoksilatnih alkilfenolov iz usnja. Posledično je pričakovati, da bosta analizni metodi pokazali podobne trende, ne pa nujno tudi enakega absolutnega rezultata pri vsebnosti alkilfenoletoksilata v usnju.
