Suitability of microwave-assisted extraction coupled with solid-phase extraction for organophosphorus pesticide determination in olive oil
(ELSEVIER SCIENCE BV, 2008-10-17)
A systematic study of the microwave-assisted extraction coupled to solid-phase extraction of nine organophosphorus pesticides (dimethoate, diazinon, pirimiphos methyl, parathion methyl, malathion, fenthion, chlorpyriphos, ...
Microwave-assisted extraction at atmospheric pressure coupled to different clean-up methods for the determination of organophosphorus pesticides in olive and avocado oil
(2009)
An effective extraction method was devised for the determination of organophosphorus pesticides (OPPs) in olive and avocado oil samples, using atmospheric pressure microwave-assisted liquid-liquid extraction (APMAE) and ...
Lanthanide sorbent based on magnetite nanoparticles functionalized with organophosphorus extractants
(National Institute for Materials Science, 2015)
In this work, an adsorbent was prepared based on the attachment of organophosphorus acid extractants, namely, D2EHPA, CYANEX 272, and CYANEX 301, to the surface of superparamagnetic magnetite (Fe3O4) nanoparticles. The ...
Simplified multiresidue method for the determination of organophosphorus insecticides in olive oil
(Elsevier B.V., 1997-02-14)
A simple and rapid method for the determination of 13 organophosphorus insecticides and their metabolites in olive oil by GC is described. The pesticide was extracted from oil with acetonitrile and no cleanup was needed. ...

Survey of organophosphorus pesticide residues in virgin olive oils produced in Chile
(2010)
Dimethoate, diazinon, parathion methyl, pirimiphos methyl, malathion, fenthion, chlorpyriphos, methidathion and azinphos methyl were determined in 71 olive oil samples produced in Chile from different varieties of olives ...
Coprecipitation-assisted coacervative extraction coupled to high-performance liquid chromatography: An approach for determining organophosphorus pesticides in water samples
(Wiley VCH Verlag, 2017-03-20)
An analytical methodology based on coprecipitation assisted coacervative extraction cop-CAE) coupled to High Performance Liquid Chromatography and UV-visible detection was developed for analysis of five organophosphorus ...
