چکیده مقاله:
The aim of this report, detection and quantification fenthion with using from Graphen quantum Dots (GQDs) as carbon sources that is as a fluorescence (FL) probe.When Fenthion was added to a GQDs solution, efficiency quenched observed .quenching as a Result of the FL charge transfer which produced strong - bond formed between GQD and Fenthion. Using of fenthion in the concentration 2.5 to 250 ʽM earn a limit of detection 0.83ʽm. Linearity of response over fenthion was demonstrate r> 0.99.
