Single Step Synthesis of Graphene Oxide Protected Silver Nanoparticles Using Aniline as Reducing Agent and Study its Application on Electrocatalytic Detection of Nitrite in Food Samples

Silver nanoparticles (AgNP) decorated reduced graphene oxide was synthesized in a single step method using aniline as reducing agent. The electrochemical behavior of the silver nanoparticles modified graphene oxide was investigated and applied for the electrochemical oxidation of nitrite at different experimental conditions. An enhanced catalytic oxidation of nitrite was noted under optimum experimental condition using AgNP/RGO modified GCE which can be utilized for the electrocatalytic detection of nitrite in food samples. The detection limit for nitrite in the above range was found to be 2.6×10-7 M.
