- Abstract
As a group of the most notorious carcinogens, N- nitrosamines (NAs) are highly toxic and usually involved in healthy issue of human daily life. An electrochemical sensor for N-nitrosodiphenylamine ( NDPhA ) detection was constructed based on graphene electrode material. The graphene was facilely obtained by direct reduction of graphene oxide (GO) with hydrazine hydrate, and further coated on the surface of the glassy carbon electrode (GCE) to fabricate the electrochemical sensor for NDPhA analysis in food samples. The present sensor showed excellent sensitivity and selectivity for the electrochemical determination of NDPhA under a reduction manner with the detection limit of 0. 6 μmol / L. It was also successfully used in beer and ham food samples with satisfactory recovery results.
