| 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. |
