Graphene, a novel class of carbon nanostructure, possesses an ultra-high specific surface area (theoretical value 2,630 m2 g−1), and both sides of the planar sheets of graphene are available for molecule adsorption. Graphene has already been used for preconcentration, extraction, and electrochemical selective determination. In this study, we used graphene to clean up pigments in cucumber for analysis,...
A method for the determination of chlorantraniliprole in six foodstuffs (including vegetables, fruits and grains) has been developed. The analyte was extracted with acetonitrile from foodstuffs and for the clean-up of raw extracts a florisil cartridge was used. Determination and quantification of chlorantraniliprole were performed by LC with an UV detector. The calibration graphs of chlorantraniliprole...
