IrO₂/Ta₂O₅ (70%:30%, molar ratio) electrodes (ITEs) were prepared by the thermal decomposition method. Typical "mud-cracked" surface and surface enrichment of Ta were observed. The determination of dopamine (DA) was carried out in the presence of ascorbic acid (AA). The detection limit of DA was 5×10^-5mol/L without the interference of AA.
