MODELS FOR THE RADIATION-CHEMISTRY OF AQUEOUS-SOLUTIONS

Diffusion kinetic calculations are used to confirm that a simple Lapla ce transform can be used to relate the radiation chemistry of aqueous solutions to the time-dependent yields of the radiation induced specie s in water in the absence of scavengers. Simple equations for the scav enger concentration dependence of the scavengable yield of e(aq)- and OH and for the yield of H-2 and H2O2 in scavenger solutions are presen ted. The time-dependent decay/formation kinetics of e(aq)-, OH, H-2 an d H2O2 are obtained from the inverse Laplace transforms of these equat ions.
