本文研究了Ｃｕ２＋ 对碱性鲁米诺阳极电致化学发光的影响，发现Ｃｕ２＋ 对发光峰强度有明显的抑制作用。通过对溶液ｐＨ 值及离子强度、溶液中支持电解质种类、鲁米诺浓度和ＥＤＴＡ 对抑制作用影响的讨论，结合Ｐｔ电极表面ＸＰＳ谱图的分析结果，给出了可能的抑制机理：非常微小的Ｃｕ（ＯＨ）２ 分子聚集体参与了电极氧化过程中双电层的形成，阻碍了电化学发光活性物质的生成和传质速率。在一定条件下，发光峰强度的减小量与Ｃｕ２＋ 浓度在６×１０－ ７ ｇ／ｍ Ｌ—５×１０－ ６ ｇ／ｍ Ｌ范围内呈线性关系。
The effect of Cu2 + on alkaline luminol anodes was studied in this paper. Cu2 + was found to have a significant inhibitory effect on the luminescence intensity. By discussing the pH and ionic strength of the solution, the type of supporting electrolyte in the solution, the concentration of luminol and the effect of EDTA on the inhibition, a possible inhibition mechanism is given in combination with the analysis of the XPS spectrum on the Pt electrode surface: a very small Cu (OH) 2 aggregates participate in the formation of electric double layer in the process of electrode oxidation, hindering the formation and mass transfer rate of the active material. Under certain conditions, the decrease of luminescence peak intensity was linear with the concentration of Cu2 + in the range of 6 × 10-7 g / m L-5 × 10-6 g / m L.
