Abstract

In the present study, a stir bar coated with hydrophilic polymer based on poly(N-vinylpyrrolidone-co-divinylbenzene) was prepd. for the sorptive extn. of polar compds. The main parameters affecting the polymn. of the coating were investigated. The new stir bar was applied successfully in stir bar sorptive extn. with liq. desorption followed by liq. chromatog.-mass spectrometry in tandem with a triple quadrupole for the detn. of a group of polar pharmaceuticals and personal care products (PPCPs) in environmental water matrixes. Different variables affecting extn. and desorption such as agitation speed, temp., ionic strength and extn. time were optimized. The results showed that the stir bar is able to enrich the selected analytes effectively. The developed method was applied to det. a group of PPCPs in different complex environmental samples, including river, effluent and influent waste water.
