ELECTROCHEMICAL DETECTION OF ACRYLAMIDE BASED ON REDUCED GLUTATHIONE BIOSENSOR

A new Nafion/GSH-Fe₃O₄/Carbon aerogels/GC electrochemical sensor was fabricated based on nanomaterials and advantages of biosensor.With optimizing the reaction condition,the optimum experimental conditions were determined as follows:the solid loading way was Nafion/GSH-Fe₃O₄/Carbon aerogels/GC,the amount of modified Carbon aerogels was 4 μL,and reaction temperature was 35℃.Under the optimum conditions,the obtained sensor presented linear response in the range of 1×10^-8to 5×10^-7mol/L and 1×10^-10to 1×10^-8 mol/L,the linear regression equation was Y₁=-0.299X+2.699 and Y₂=-15.272 76X+167.679 91.The detection limit was 8.87×10^-11mol/L.
