| 摘 要： | 在单壁碳纳米管(SWCNT)表面修饰Cu(sal-β-Ala)(3,5-DMP_2)]玻碳电极(GCE),该修饰电极不仅对多巴胺(DA)和尿酸(UA)具有很好的电化学催化效果,而且对它们有很强的检测能力.Cu(sal-β-Ala)(3,5-DMP_2)]修饰电极对DA的检测线性范围为10~210 mmol/L,检测极限为7.29μmol/L;而对UA的检测线性范围为从1~86mmol/L,检测极限为1.5μmol/L.同时,利用微分脉冲伏安法(DPV)来测定DA和UA,相比之下,Cu(sal-β-Ala)(3,5-DMP_2)]与单壁碳纳米管及修饰玻碳电极结合具有良好的灵敏度和分辨率.

Electrochemically Determining Dopamine and Uric acid by Cu(sal-β-Ala) (3,5-DMP2)-SWCNTs Modified Glassy Carbon Electrode |

| Abstract: | Cu(sal--Ala)(3,5-DMP2)] is modified on the surface of the single-walled carbon nanotubes (SWCNTs) glass carbon electrode (GCE). The modified electrode shows impressive detection ability of dopamine (DA) and uric acid (UA). The modified electrode has a good electrocatalytic effect on DA and UA. The detection linear range of Cu(sal--Ala)(3,5-DMP2)] to DA is 10.00 to 210 mmol/L and the detection limit is 7.29 mol/L. While, the detection linear range of Cu(sal--Ala)(3,5-DMP2)] to UA has a good linear range from 1 to 86 mmol/L and the detection limit is 1.5 mol/L. In this work Simultaneous Differential Pulse Voltammetric (DPV) is employed to determine DA and UA. DPV method with Cu(sal--Ala)(3,5-DMP2)]/SWCNTs/GCE has a good sensitivity and resolution rate. |
