摘要：
A platform based on praseodymium doped dysprosium oxide-carbon nanofibers modified electrode was constructed for the simultaneous determination of SY and TAR. SEM, EDX and XRD techniques were utilized for characterizing the proposed material. The voltammetric behaviour and properties of SY and TAR were gradually improved at materials in order from CNFs to Dy2O3-CNFs and Pr6O11@Dy2O3-CNFs. The working range was found to be 1.0x10(-9)-3.5x10(-8) M and 1.5x10(-9)-4.0x10(-8) M for SY and TAR, respectively. The value of LOD was 3.12x10(-10) M and 5.35x10(-10) M for SY and TAR, respectively. The platform (Pr6O11@Dy2O3-CNFs/GCE) was successfully applied to the electroanalysis of samples.
