phthalic acid/dichloromethane

A method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) was developed for the determination of phthalic acid esters (PAEs) in soil. The soil sample was extracted by dichloromethane-acetone (1: 1, v/v) with an ultrasonic instrument, and the extract was cleaned up with a Florisil

A sensitive and effective analytical method has been optimized and validated for the determination of particulate and gaseous phthalic acid esters (PAEs) in ambient air. The samples were Soxhlet extracted with an n-hexane-dichloromethane-methanol mixture (1:1:1, volume ratio), and analyzed using

In this work, the first application of core-shell poly(dopamine) magnetic nanoparticles as sorbent for the extraction of a group of eleven phthalic acid esters of interest (i.e. diethyl phthalate (DEP), dipropyl phthalate (DPP), dibutyl phthalate (DBP), bis-isopentyl phthalate (DIPP), bis-n-pentyl

Phthalates are ubiquitous in the environment and thus exposure to these compounds can occur in various forms. Foods are one source of such exposure. There are only a limited number of studies that describe the levels of phthalates (diesters, monoesters and phthalic acid) in foods and assess the

Bioplastic materials are increasingly used due to its benefits for the environment preservation. Among them, food packaging materials based on polylactic acid (PLA) are among the most employed. In this work, a sample treatment methodology based on dissolution/precipitation has been optimized,
