Paper Abstract

Investigation of the destruction of 2,4-dichlorophenoxyacetic acid (2,4-D) under the influence of UV radiation from the KrCl excilamp with the use of additives of hydrogen peroxide, the Fenton reagent. Effective rate constants of degradation reactions of the initial compound were calculated. The estimation of efficiency of both each system separately, and together is given. The use of hydrogen peroxide additives and Fenton's reagent is due to the fact that the use of direct photolysis in some systems is ineffective. Addition of hydrogen peroxide in such cases increases the efficiency, due to the formation of active forms of oxygen in aqueous solutions. Thus, studies have been carried out to find the most effective amount of hydrogen peroxide additive and to create the most effective system for the destruction of chlorinated phenoxy acids when excited by a KrCl excilamp (222 nm).
