Chain decomposition of disodium salt of chromotropic acid in aqueous solution under γ-irradiation effect

Radiolysis of aqueous solutions of disodium salt of chromotropic acid has been studied depending on the dose rate, initial concentration, and pH. It has been established that in aqueous aerated and deaerated solutions the chain process takes place which is initiated by hydroxyl radicals. The rate of the chain process depends on the initial pH value, the dose rate and the initial salt consentration being fixed. The absorption spectra of short-lived radiolysis products have been obtained. The rate constants of recombination of these products have been calculated
