标准范围
This part of ISO 18218 is a method for determining alkylphenols (nonylphenol and octylphenol)and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather andprocess auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gaschromatography-mass spectrometry (GC-MS).The analysis of the alkylphenol ethoxylate is made by cleaving the alkylphenol ethoxylate and measuringthe released alkylphenol.NOTE ISO 18218-1 and this part of ISO 18218 use different solvents for the extraction of the ethoxylatedalkylphenols from leather. Consequently, the two analytical methods are expected to give similar trends but notnecessarily the same absolute result for the ethoxylated alkylphenol content in leather.
