Abstract
The decay of solvated electrons in various aqueous solutions was studied using a stroboscopic pulse radiolysis technique with a time resolution of 24 psec. High concentrations of solutes such as H2O2, acetone, CdCl2, NaNO2, and NaNO3 decreased the initial solvated electron yield, while high acid concentrations did not. Reasons for this reduction in yield are discussed, and the conclusion reached is that the scavengers must be reacting with a precursor to the solvated electron. We believe that this precursor is probably a low‐energy electron which reacts prior to solvation.
