A novel application of three phase hollow fiber based liquid phase microextraction (HF-LPME) for the HPLC determination of two endocrine disrupting compounds (EDCs), n-octylphenol and n-nonylphenol, in environmental waters

► First time of use of three phase HF-LPME for the extraction of octylphenol and nonylphenol ► Complete study of experimental HF-LPME parameters ► Excellent HPLC baselines even analyzing complex matrices ► Application to the determination in environmental waters including urban wastewaters
