摘要: Abstract We have applied a method based on solid-phase extraction (SPE), on-line coupled to gas chromatography–mass spectrometry through an on-column interface, determine group of endocrine-disrupting compounds in water samples. optimised the parameters affecting SPE process and transfer step used analyse river, coastal tap waters. In full-scan acquisition mode, all were determined by preconcentrating only 15 ml sample. Di-n-butyl phthalate, benzylbutyl bis(2-ethylhexyl) phthalate adipate at concentrations between 0.02 0.5 μg l−1 some real
