Abstract

A platinum electrode was chemical modified with acetanilide-Co2+ by square cyclic voltammetry method(SCV) in pH=5.0 three acid(H3PO4-H3BO3-HAc) buffer solution for the determination of aspartic and taurine acid

and the experimental conditions were optimized.The results show that the modified platinum electrode has good stability and reproducibility.For aspartic and taurine acid

the linear range is 4.0×10-9

.0×10-6 mol/L and 2.0×10-7

.0×10-5 mol/L

respectively.The detection limit is 1.0×10-9 mol/L and 2.0×10-8 mol/L respectively.The recovery rate is about 97% and about 95% respectively.The method has the advantages of high sensibility and low detect limit

and can be applied to the determination of aspartic and taurine acid by SCV.
