摘要：

Reduction of Ag+ ions in aqueous solutions containing Zn2+ ions was studied by a pulse radiolysis technique. It was found that the Zn+ Species formed reduce Ag+ in the electron transfer reaction at a rate constant 2 x 10(9) l mol(-1) s(-1). The rate constants 2k(Zn+ + Zn+) = 2.5 x 10(9) l mol(-1) s(-1), k(Zn+ + CO2-) = 9.5 x 10(9) l mol(-1) s(-1), and k(Zn+ + CH3CHOH) = 1.9 x 10(9) l mol(-1) s(-1) were determined. Features of the mechanism of radiation-chemical transformations in the presence of ethanol and formate ions are discussed.
