Pulse radiolysis studies on aqueous systems PtCl42−Cl− and PtCl42−Br−
Pulse irradiation of PtCl42− in aqueous solutions containing Cl− or Br− indicates that oxidation of Pt(II) by OH may be wholly or partially replaced by oxidation by Cl2− or Br2−, depending on the efficiency of OH scavenging by the particular halide ion. The Pt(III) species produced by the latter reactants absorb respectively at 290 and 310 nm and differ from that produced by OH. Contrary to the similar PdCl42− no evidence of Pt(II) co-ordinating more than four Cl− ions has been obtained. The rate constants of the processes and extinction coefficients of the transient species observed are reported.
