Degradation and detoxifi cation of 2-chlorophenol aqueous solutions using ionizing gamma radiation
Chlorophenols are widely used in various industries, including as preservatives in wood manufacturing, in paper industry, in chemical synthesis, and in biodegradation of herbicide and pesticide [1]. These applications lead to considerable level of contamination in wastewater and ground water [2]. Chlorophenols are highly toxic, poorly biodegradable, and present serious health concerns to human ...
متن کاملPreparation and characterization of Epoxy/Lead oxide nano-composite for shield against gamma and X-rays
Polymer nano-composites are a group of materials that represent proper mechanical, chemical, thermal and optical properties due to the presence of certain percentages of a filler in a polymeric matrix. In this study lead oxide nanoparticles were prepared by direct precipitation method. Then the lead oxide-epoxy resin nanocomposite was prepared by mixing (without solvent) with different weight p...
متن کاملPhotocatalytic Degradation of 4-Chlorophenol. 2. The 4-Chlorocatechol Pathway
The TiO2-mediated photocatalytic degradation of 4-chlorocatechol is studied as a branch of the degradation of 4-chlorophenol. In addition to some basic kinetic studies, the identities of many of the cyclic and acyclic intermediates, verified in most cases with authentic samples, are reported. From 4-chlorocatechol, the major product is hydroxylation to form 5-chloro-1,2,4-benzenetriol. A small ...
