Simultaneous Determination of Uric Acid, Xanthine and Hypoxanthine Based on poly(3-Amino-5-mercapto-1, 2, 4-triazole)/Multi-walled Carbon Nanotubes Modified Glassy Carbon Electrode
摘要
Abstract
In this paper,the poly (3-amino-5-mercapto-1,2,4-triazole)/multi-walled carbon nanotubes modified glassy carbon electrode(pTA/MWCNTs/GCE) was successfully prepared by electrodepositing 3-amino-5-mercapto-1,2,4-triazole(TA) on the MWCNTs/GCE.The electrochemical behaviors of uric acid (UA),xanthine (XA) and hypoxanthine (HX) at the pTA/MWCNTs/GCE were investigated using cyclic voltammetry (CV) and differential pulse voltammetry (DPV).The results showed that the chemically modified electrode displayed excellent electrochemical catalytic activities towards UA,XA and HX.The calibration curves for UA,XA and HX were obtained over the ranges of 9.0-739.0,2.0-259.0,1.0-353.0 μmoL/L with the detection limits of 0.67,0.17,0.33 μmol/L,respectively.In addition,the modified electrode was applied in the determination of UA,XA and HX in real samples (urine and serum),with the recoveries of the samples ranged between 98.8%-105.5%.关键词
