摘要
A poly(2-Amino-Phenol-P-Sulphonic acid)Modified Electrode was prepared by cyclic voltammetry and the electrochemical behavior of Uric Acid(UA)on this modified electrode was studied.The result was showed that this modified electrode has strong electrocatalytic functionality for UA,and strong anti-jamming impact for Ascorbic acid(AA).In pH=5.6 KH2PO4-Na2HPO4 buffer solution,use cyclic voltammetry and difference pulse voltammetry,the linear rang for determining UA was 8.0×10-6mol/L~2.0×10-4 mol/L(CV)and 4.0×10-7mol/L~1.0×10-5mol/L(DPV),The detection limit is 6.0×10-6 mol/L and 1.0×10-7 mol/L.Use of this method for measurement of UA in urine obtained satisfactory results.
A poly (2-Amiuo-Phenol-P-Sulphonic acid )Modified Electrode was prepared by cyclic vohammetry and the electrochemical behavior of Uric Acid (UA)on this modified electrode was studied. The result was showed that this modified electrode has strong electrocatalytic functionality for UA, and strong anti-jamming impact for Ascorbic acid ( AA ). In pH = 5.6 KH2PO4-Na2 HPO4 buffer solution, use cyclic voltammetry and difference pulse voltammetry, the linear rang for determining UA was 8. 0 × 10^-6Smol/L -2. 0 × 10^-4 mol/L(CV) and 4. 0 × 10^-7mol/L - 1.0 × 10^-5mol/L(DPV) ,The detection limit is 6. 0 × 10^-6s mol/L and 1.0 ×10^-7 mol/L. Use of this method for measurement of UA in urine obtained satisfactory results.
