| 英文摘要 | A glassy carbon electrode (GCE) was modified with electropolymerized films of amidosulfonic acid in pH 7.0 phosphate buffer solution (PBS) by cyclic voltammetry (CV). The modified electrode showed an excellent electrocatalytical effect on the oxidation of dopamine (DA). In pH 7.0 PBS, the anodic peak current increased linearly with the concentration of DA in the range of 5.0x10(-7)similar to 1.0x10(-4) mol dm(-3), with a correlation coefficient of 0.9932, and a detection limit (S/N=3) of 1.0x 10(-7) mol dm(-3). The relative standard deviation of 10 successive scans was 2.5% for 1.0x10(-6) mol dm(-3) DA. The interference of ascorbic acid (AA) with the determination of DA could be eliminated because of the very distinct attracting interaction between DA cations and the negatively poly(amidosulfonic acid) film in pH 7.0 PBS. The proposed method exhibited good recovery and reproducibility. |
