## Abstract Nonylphenol ethoxylates (NPEO~x~) are surfactants which are used worldwide and can be transformed in the environment by microorganisms to form nonylphenol (NP). Analysis of these compounds was carried out with micellar electrokinetic capillary chromatography (MEKC). Different parameters
We have developed a method for ascertaining the presence of nonylphenol (NP) and nonylphenol ethoxylates (NPEs) in pulp samples at very low levels. The method entails pre-concentration of the compounds and their detection by Py-GC/MS. Solvent extraction of the compounds from pulps with acetone gives
