| Abstract: | Abstract The DC polarographic behavior of the Cu(II)-inosine complex was investigated, in aqueous solutions of inosine in Britton Robinson buffer solutions at pH's from 1.0 to 4.0. At low concentrations of free inosine ion, only one polarographic wave was found corresponding to a two-electron reduction. Anisotropy of g/ = 2,039, g// = 2,287 and A// = 172G, A/= OG, was observed in the ESR spectrum of the Cu(II)/inosine complex. When the composition ratio of the complex was obtained by both polarography and ESR, it was found that the ratio Cu(II) to inosine was 1:2. The polarographic wave showed a two electron reduction wave. |
