Simultaneous determination of six phthalate esters in bottled milks using ultrasound-assisted dispersive liquid-liquid microextraction coupled with gas chromatography.

Abstract

A new method was developed for the simultaneous determination of six phthalate esters in bottled milks using ultrasound-assisted dispersive liquid-liquid microextraction (UA-DLLME) followed by gas chromatography-flame ionization detection (GC-FID). 0.8 mL of methanol (dispersant) and 40 μL of CCl(4) (extractant) were injected into 8.0 mL of milk solution… (More)
