| 摘要: 在0.02mol/L NaHCO3-0.05mol/L Na2SO4(pH9)介质中,对鸟嘌呤与Cu(Ⅰ)的配位作用进行了极谱研究,测定了鸟嘌呤与Cu(Ⅰ)配位的配体数(2)和该配合物的条件形成常数(β1=1.80×1014,β2=2.85×1018),并对DcFord-Hume公式的适用性作了讨论. |

| Abstract: By means of D.C. polarography, the coordination of guaninc with Cu(I) was studied in the system of 0.02mol/L NaHCO3-0.05mol/L Na2SO4(pH9). The complexes are irreversibly reduced at the dropping mercury electrode. DcFord-Hume's method was used for the determination of the coordination number and the conditional formation constants of Cu(I)-guanine complexes. The results are 1.80×l014(CuG) and 2.85×l018(CuG2), respectively, and the adapt of DcFord-Hume's equation was discussed briefly. |
