Adsorption of aromatic hydrocarbons and ozone at environmental aqueous surfaces.
Adsorption of environmentally important aromatic molecules on a water surface is studied by means of classical and ab initio molecular dynamics simulations and by reflection-absorption infrared spectroscopy. Both techniques show strong activity and orientational preference of these molecules at the surface. Benzene and naphthalene, which bind weakly to water surface with a significant contribut...
متن کاملadsorption of polycyclic aromatic hydrocarbons on activated carbons: kinetic and isotherm curve modeling
the modeling of kinetic and isotherm curves acquired in adsorption of polycyclic aromatic hydrocarbons (pahs) as a model compound (phenanthrene) on activated carbons in the organic solvent. all the runs were carried out in a batch system at atmospheric pressure, process temperature of 24±2°c, and using the 100 ml phenanthrene in cyclohexan. this experimental work was mainly focused on the study...
متن کاملDegradation of Aromatic Hydrocarbons
Aromatic hydrocarbons are widely distributed in nature. They are found as lignin components, aromatic amino acids and xenobiotic compounds, among others. Microorganisms, mostly bacteria, degrade an impressive variety of such chemical structures. A broad range of peripheral reactions results in a restricted range of central intermediates, which are subject to ring-cleavage and funneling into the...
متن کاملcata-condensed aromatic hydrocarbons
A large fraction (30 of 62) of the cata-condensed polycyclic benzenoid aromatic hydrocarbons with one to six rings have nonplanar pi carbon atom frameworks, with the minimum angle of nonplanarity approximately 30°. In addition to 17 pairs of enantiomers, four of the nonplanar cata-condensed benzenoids with six rings are redicted to be capable of existing as pairs of twisted diastereoisomers. Ma...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
