A hybrid material as a sorbent phase for the disposable pipette extraction technique enhances efficiency in the determination of phenolic endocrine-disrupting compounds

Autor: Josias Merib, Hérica A. Magosso, Eduardo Carasek, Otávio R. Bittencourt, Gabriela Corazza

Publikováno v: Journal of Chromatography A. 1513:42-50

In this study, the hybrid material 3-n-propyl(3-methylpyridinium) silsesquioxane chloride (Si3Py+Cl-) was synthesized and investigated as a novel sorbent phase for the disposable pipette extraction (DPX) technique coupled to high-performance liquid c
