| 摘 要： | 系统研究了鲁米诺体系的电致化学发光行为 ,发现电学参数和溶液的酸碱性很大程度地影响电化学发光的产生、光强及连续性。确定了在碱性环境中的最佳电化学发光条件 ,发现在 KOH- KCl( p H=12 .5)介质中 ,于 Pt电极上施加 +1.3V( vs.Ag/ Ag Cl)的正矩形脉冲 ,可得到鲁米诺的最佳发光信号。发光强度与鲁米诺的浓度在 1.0× 10 -7— 1.0× 10 -5mol/ L范围内呈线性关系。并讨论了 H2 O2 及硫脲对鲁米诺的电致化学发光的影响。

| Abstract: | The electrochemiluminescence(ECL) behaviour of luminol was systematically studied.It is obviously influenced by the electric parameters and acidity of the solution. The optimal ECL signal of luminol was occurred in the alkali medium (pH=12. 5) and excited by the right orthogon pulse with the amplitude of 1.3V(vs. Ag/AgC l) on the Pt electrode.In the range of 1.0×10-7- 1.0×10-5 mol/L, the luminous intensities of ECL are linear correlation to the concentration of luminol. Furthermore, the affections of H2O2 and thiourea on the ECL of luminol were also studied. |
