Abstract(#br)Phthalates are a group of synthetic compounds mainly used as plasticizers, which have been classified as endocrine-disrupting chemicals and potential human-cancer causing agents. They can be found in high amounts in foods, deriving mainly from plastic packaging. The analytical determination of these compounds is very challenging since they are ubiquitous. Therefore, minimization of sample manipulation is highly desirable.(#br)The present work exploited the application of a solid-phase microextraction method for the analysis of phthalates in vegetable oil.

Abstract(#br)A polyacrylonitrile (PAN)/polydimethylsiloxane (PDMS) membrane supported with an appropriate quantity of titanium dioxide (TiO 2 ) nanoparticles was electrospun. The membrane was used in a two-phase electromembrane extraction (EME) setup for extracting diethylhexyl phthalate (DEHP) from aqueous samples.
