Photolysis and radiolysis of monochloroacetic acid in aqueous solution

Advancements of radiation induced degradation of pollutants in drinking and waste water

The radiation induced decomposition of some water pollutants such as chlorinated methanes, ethanes and olefines has been studied under various conditions. In addition to product analysis, spectroscopic and kinetic characteristics of CH3, C2H5 and their peroxides were also reinvestigated by pulse radiolysis techniques. Based on the experimental results, probable reaction mechanisms for the decomposition of some pollutant systems are presented. At the same time the present state of the research in this field is given.

Radiation induced decomposition of biological resistant pollutants in water

Data and reaction mechanisms for oxidative decomposition of biological resistant chlorinated hydrocarbons in aerated water under the influence of ionizing radiation are reported. The radiolysis of the pollutants was studied as a function of the absorbed radiation dose, whereby the formation of C1- ions served as an indicator for the degradation process. In addition phenol was also investigated as a representative of aromatic compounds. Based on the experimental data a radiation pretreatment of water is proposed followed by conventional methods for water purification.
