Radiolysis of oxalic and citric acids using gamma rays and accelerated electrons

The radiation technique was tested as a method for degradation of organic complexants in spent decontamination solutions. Aqueous solutions containing oxalic and/or citric acid were irradiated under different conditions. Kinetics of radiolysis of both acids was studied; the effects of various parameters, presence of inorganic ions and saturation by various gases on their degradation were investigated. Results show that irradiation leads to a sufficient degree of removal of both acids from the solution.
