铜－黄嘌呤核苷络合物极谱伏安行为的研究①樊惠芝刘金龙②潘景浩＊（山西大学化学系太原０３０００６）黄嘌呤核苷（ｘａｎｔｈｏｓｉｎｅ）是重要的生物大分子之一，前人曾用分光光度法、薄层色谱法、纸层色谱法等方法对其进行了定性、定量分析；用ＰＧＥ电极对其电化学...
The polarographic and voltammetric behaviour of Cu(Ⅱ) xanthosine complex has been studied. A new sharp reduction peak is yielded at the potential of -0.14 V(vs, Ag/AgCl). The conc. of Cu(Ⅱ) is proportional to peak current of NPP in the range of 1×10 -6 ～1×10 -4 mol/L when the conc. of xanthosine is 1×10 -4 mol/L. It is indicated that the current has adsorption character. The mechanism of the electrode reaction was deduced and the ratio of the complex is Cu(Ⅱ) ∶ xanthosine=1∶1.
