Novel coatings for stir bar sorptive extraction to determine pharmaceuticals and personal care products in environmental waters by liquid chromatography and tandem mass spectrometry
Abstract(#br)Two new commercially available polar coatings for stir bar sorptive extraction (SBSE), consisting of polyacrylate (PA) with a proportion of polyethyleneglycol (PEG) (Acrylate Twister ® ) and PEG modified silicone (EG Silicone Twister ® ), were evaluated and compared with the classic coating based on polydimethylsiloxane (PDMS Twister ® ) for the extraction of a group of pharmaceuticals and personal care products (PPCPs) from wastewater samples.(#br)The SBSE parameters, such as sample pH, agitation speed, extraction temperature, extraction time, desorption solvent and time, were op
