Preparation and Characterization of PSS/Pt/GR/GCE Graphene Composite Modified Electrode
Keywords:Graphene composite modified electrode, Characterization, Tyrosine
The Poly(Sodium Styrenesulfonate) / nano Pt / graphene (PSS/Pt/GR) composite modified electrode material was prepared and characterized by transmission electron microscopy(TEM), infrared spectroscopy and alternating current impedance. The electrochemical behavior of tyrosine was determined on PSS/Pt/GR/GCE composite modified electrode. The results show that the PSS/Pt/GR composite modified electrode material is synthesized well. This electrode can be used to determine tyrosine with high sensitivity and accuracy, which could have promising applicability for the determination of other substances.
