The present paper shows that the reagent 2,9-dimethyl-l,10-phenanthroline (which we called as new copperon) reacts with hydrogen peroxide in alkaline solution, in the presence of metallic ion, such as Cu(Ⅱ), Pb(Ⅱ), Cod), Fe(Ⅲ) and Ni(Ⅱ) respectively, as a catalyst to produce chemiluminescence of a greenish color. The mechanism of this chemiluminescence reaction has been discussed in the present paper and is believed that a peroxy-icn is formed from hydrogen peroxide by the catalytic reaction of the complex of...

The present paper shows that the reagent 2,9-dimethyl-l,10-phenanthroline (which we called as new copperon) reacts with hydrogen peroxide in alkaline solution, in the presence of metallic ion, such as Cu(Ⅱ), Pb(Ⅱ), Cod), Fe(Ⅲ) and Ni(Ⅱ) respectively, as a catalyst to produce chemiluminescence of a greenish color. The mechanism of this chemiluminescence reaction has been discussed in the present paper and is believed that a peroxy-icn is formed from hydrogen peroxide by the catalytic reaction of the complex of Cu(Ⅱ) with the new coppercn in the process, and the peroxy-ion is then reacts with the new copperon to produce the chemiluminescence emission. The product of this chemiluminescence reaction has been separated out by thin layer chromatc-graphy and determined by various methods, such as UV, IR and fluorescence spectrophotometry respectively.In addition, the analytical application of this new chemilumineselce reaction has been carried out in our laboratory, and the determination of Cu(Ⅱ) with the chemiluminsecence system is shown in this paper. The lower detection limit of Cu is e×10-9. The linear range of response is 1×10-8 to 4×10-7g/ml. No effect of foreign ions, except certain, amounts of Co(Ⅱ), Mn(Ⅱ) Ni(Ⅱ) Cd(Ⅱ), and Cr(Ⅲ) respectively for the determination of 0.1 ppm Cu(Ⅱ). It can be applied satisfactorily to the determination of Cu in alumnum alloy.

本文阐明了试剂2,9-二甲基-1,10-菲咯啉(称为新铜灵)在金属离子诸如Cu(Ⅱ)、Pb(Ⅱ)、Fe(Ⅲ)和Ni(Ⅱ)作为催化剂各自存在下,可与过氧化氢在碱性溶液中产生一种绿色的化学发光反应。此化学发光反应的机理已在本文中进行讨论,并认为是由于Cu(Ⅱ)与新铜灵生成之络合物在此过程中进行催化反应而致使过氧化氢生成超氧基离子,而此超氧基离子随即与新铜灵试剂作用产生化学发光。此化学发光反应的产物已用薄层色谱法进行分离,并且分别用紫外、红外和荧光分光光度法进行测定。 此外,这种新的化学发光反应已在我们实验室进行了分析应用试验。用此化学发光体系来做Cu(Ⅱ)的测定也在本文中说明。此法测铜的检测下限为8×10~(-9)克/毫升;线性范围是1×10~(-8)到4×10~(-7)克/毫升。对于0.1ppm之铜的测定而言,除适量的Co(Ⅱ),Mn(Ⅱ)、Ni(Ⅱ)、Cd(Ⅱ)和Cr(Ⅲ)之外,其余外来离子均无干扰。这一分析方法能够满意地用于铝合金中铜的测定。
