| 摘 要： | IrO2Ta2O5 (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 5 mol/L without the interference of AA.
