Abstract
It has been shown that frozen (methanol, ethanol, ethylene glycol, glycerol)-water containing LiCl, MgCl 2 or CaCl 2 are very convenient matrices for studying radiation-chemical processes using optical methods. Gamma irradiation of such systems brings about two primary products, Cl 2 - and e 2 - possessing strong absorption bands the intensity of which can be controlled by adjusting the composition of the matrix. The effectiveness of electron scavenging by nitrates, chromates, formic acid, acetylacetone and 2,2'-bipyridyl have been determined. It has been shown that the apparent electron scavenging effectiveness depends on the composition and structure of the matrix and is closely connected with the concentration of electron traps.
