Separation and preconcentration of inorganic Se species in tap and natural waters using unfunctionalized nanosilica as sorption material in dispersive micro-solid phase extraction
(Elsevier Science, 2019-01)
A highly sensitive and selective method based on dispersive micro-solid phase extraction (D-μ-SPE) technique was developed for the determination of inorganic Se species. A very simple and fast preconcentration procedure ...
Matrix solid-phase dispersion associated to gas chromatography for the assessment in honey bee of a group of pesticides of concern in the apicultural field
(Elsevier B.V., 2018)
A method based on matrix solid-phase dispersion (MSPD) associated to gas chromatography-flame photometric detection (GC-FPD), GC-electron capture detection (GC-ECD) and GC-mass spectrometry (GC-MS) for confirmation purposes, ...
Magnetic hybrid support for ultrasound-assisted magnetic solid-phase extraction of polycyclic aromatic hydrocarbons from produced water
(2019-05-01)
This work describes the synthesis of two hybrid organic-inorganic supports with magnetic properties, using water with a high content of natural organic matter (NOM) as solvent and to compose the organic phase. The materials ...
