摘要：
The radiation reduction of bis(1-ethylimidazole)tartratoplatinum(II) (EITPt(II)) complexes in methanol-water solutions have been examined. The yields of Pt(I) depend on the presence of O-2 in solution as well as the dose applied. The rate constants of e(s)(-) scavenging by EITPt(II) and cis(diammine-1,1-cyclogutanedicarboxylato)platinum(II) (CBDCAPt(II)) have been determined by pulse radiolysis to be equal to 5.4 x 10(9) and 6.4 x 10(9) M-1 s(-1), respectively. The efficiencies of e(t)(-) scavenging by EITPt(II) and the rate of e(t)(-) photobleaching have also been determined in LiCl:H2O:CH3OH and MgCl2: H2O : CH3OH glasses, respectively.
