Abstract

In this study, a simple and fast magnetic dispersive solid phase extraction methodology was developed G@Fe3O4/Fe/Ag nanoparticles for preconcentration and determine of phenolic compounds in water samples. The sorbent was characterized by assorted characterization method.
The effects of diverse factor on the extraction process were studied thoroughly via design of
experiment and desirability function. This work was showed the G@Fe3O4/Fe/Ag NPs was the best sorbent between Graphene, G@Fe3O4/Fe and Fe3O4, 0.01M HNO3in acetonitrile was the most efficiency between eluent types, the best salt content which was 7.5% w/v.
