Abstract
Graphene oxide (GO) and its functionalized systems have very unique structural advantages as excellent adsorbent or substrate material in the removal of organic contaminants. Herein, we reported a strategy to establish functionalized GO system (FGO) using amphiphilic molecules didodecyldimethylammonium bromide (DDAB) as a modifier for the detoxification of zearalenone (ZEN) from corn oil. The adsorption property for the removal of ZEN from edible corn oils under different experimental conditions such as pH, amphiphilic molecules, time and temperature was investigated in detail. The morphology structure, adsorption isotherm, adsorption kinetics and the recyclability of FGO systems have also been researched, systematically. The FGO systems exhibit a higher adsorption efficiency, recyclability and thermostability in comparison with the traditional adsorbent materials. It provides an insight into the detoxification of mycotoxin from edible oils by graphene-based new materials.
