Graphene is a novel class of carbon nanostructures which possess an ultra-high specific surface area. It has already been used for pre-concentration, extraction, and electrochemical selective determination of pesticides but not much work has been focused on the cleanup efficiency of graphene. In this work, graphene was evaluated as an alternative cleanup sorbent for gas chromatography-mass spectrometry (GC-MS) analysis of 17 pesticides analyzed in vegetables and fruit with the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method. QuEChERS is a standard method published by CEN (European Committee for Standardization) Code EN 15662: 2008. The recoveries of the 17 pesticides in carrot, grape, tomato and rape were 92-120 % with relative standard deviations below 10 %. Comparative studies showed that graphene not only has good removal efficiencies of pigments in vegetables and fruit, but also has better cleanup ability than commonly used graphitized carbon black (GCB).
