A miniaturized graphene-based pipette tip extraction (M-G-PTE) method coupled with liquid chromatography-ultraviolet detection was developed for rapid screening of sulfadimidine, sulfachloropyridazine, sulfamonomethoxine, and sulfachloropyrazine residues in bovine milk. Because of the large surface area and unique chemical structure of graphene, an M-G-PTE device packed with 3.0mg graphene could handle...
Organic solvents were widely used for extraction of bioactive compounds from different functional foods and nutraceuticals. However, the involvement of toxic and volatile organic solvents causes significant environmental problems. In order to overcome the shortages, non-ionic surfactant-assisted extraction was proposed as an alternative, effective, cheap and green extraction method. By considering...
