N2 - The effect of CdSO4 and NiSO4 on the radiolytic hydrogen yield and its isotopic composition in the systems H2O + CH3OH, H2O + CD3OH, D2O + CH3OD, H2O + (CH3)2CHOH, H2O + (CH3)2 CDOH and D2O + (CH3)2CHOD are reported. The results suggest that hydrogen atoms and aliphatic radicals oxidize Cdaq+ and Niaq+. Furthermore it is suggested that the reaction Cd-C(CH3)2OH+ → CdH+ + (CH3)COH=CH2 occurs in aqueous solutions. The implications of these observations on earlier results are discussed.
