CEN - EN ISO 18218-2

Leather - Determination of ethoxylated alkylphenols - Part 2: Indirect method

inactive
Organization: CEN
Publication Date: 1 June 2015
Status: inactive
Page Count: 24
ICS Code (Leather and furs): 59.140.30
scope:

This part of ISO 18218 is a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries.The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS).

The analysis of the alkylphenol ethoxylate is made by cleaving the alkylphenol ethoxylate and measuring the released alkylphenol.

NOTE ISO 18218-1 and this part of ISO 18218 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.
