Alkyl phenol ethoxylates (APEOs), particularly nonyl phenol ethoxylates (NPEOs), are non-ionic surfactant components used in woollen-yarn spinning oils and industrial detergents. In recent years, concern over the hormone-disrupting properties of NPEOs has given rise to proposals to ban their use in EU countries. A sensitive and reliable method of detecting NPEOs on incoming raw material and in textile effluent is therefore required. A method has been developed to detect NPEOs at ppm levels in wool-scouring effluent by the application of extraction and clean-up procedures followed by high-performance-liquid-chromatography (HPLC) analysis.
