A simple procedure for the synthesis of magnetic hybrid nanoparticles (MHNP) was developed by combining multi-walled carbon nanotubes modified by microwave energy and magnetic iron oxide nanoparticles. MHNP were introduced as sorbents in a magnetic s

Natural deep eutectic solvents (NADES) were introduced for the extraction of free seleno-amino acids from lyophilized and powdered milk samples. Different NADES were evaluated, and lactic acid:glucose (LGH) showed the highest selenium recoveries. Sel

Oxidized multiwall carbon nanotubes (oxMWCNTs) were combined with TiO2 nanoparticles to obtain hybrid nanoparticles (HNPs). A miniaturized flow injection (FI) system was introduced for antimony speciation and a headspace vial was used for hydride gen
