| Abstract: | The conditions of preparing for prussian blue（PB） modified glassy carbon electrode（PB/GCE） and the electrochemical kinetics of Uric acid（UA） at PB/GCE were studied.The charge transfer coefficient α,the reaction order and reaction rate constant k were measured with electrochemical method for the UA in the PB/GCE.It was shown that PB/GCE exhibits a significant catalytic effect toward the oxidation of Uric acid（UA）,charge transfer coefficient α was 0.65,reaction order was 1,catalytic reaction rate constant k was 1.98×103（mol·L-1）/s.This method has ability of anti-interference and easy operation. |
