Chloroaromatics are widely distributed organic pollutants in the environment. These compounds are classified as high priority ecotoxicants due to their persistence,carcinogenicity and low biodegradability. It is known that the adsorption of the organic species is an important factor for the highly efficient decomposition process....

The photocatalytic processes are normally implemented in an oxygen mediated aqueous environment. Therefore, the TiO2-water and TiO2-oxygen systems are of principal and practical interest in this field....

The purpose of studying the point kinetics equations, which are solved numerically using the stiffness confinement method (SCM). The difficulty in the numerical solution of these equations is due to the stiffness of the system arising from the difference order of magnitude between the prompt and delayed neutron lifetimes....
