DETERMINATION OF ETHOXYLATED NONYLPHENOL AND OCTYLPHENOL IN LEATHER BY CLEAVAGE TREATMENT COMBINED WITH GC-MS

摘要

Alkylphenol ethoxylates (APEO), are a major group of nohionic surfactants, which have been widely used as emulsifiers, dispersive and auxiliary agents in fine chemicals. In most cases, APEO referred exclusively to nonylphenol ethoxylates -NPEO and octylphenol ethoxylates-OPEO, both are by far the most commonly used and encompass more than 98% of APEO market. All the liquid auxiliaries used for leather-marking are possibly containing APEO.
