Thermodynamics of Mobile Order Theory: Solubility and Partition Aspects
… polycyclic aromatic hydrocarbons (biphenyl, acenaphthene, and phenanthrene), and the organometallic ferrocene were studied in a wide array of solvents. Mobile order theory predictive equations were derived and percent average absolute deviations between experimental and calculated mole …

Effects of Grasses on the Remediation of Creosote-Contaminated Surface Soil
… of 15 to 21 cm, and the six most prevalent PAHs, acenaphthene, fluorene, phenanthrene, fluoranthene, pyrene and chrysene were quantified. Data from four sampling periods, t=0, 9, 12 and 17 months is presented. At t=9 months, substantial loss of the five lowest molecular weight (LMW) PAHs had …

Characterization of a Creosote-Contaminated Tie Yard Site and the Effects of Phytoremediation
… for 6 polycyclic aromatic hydrocarbons (PAHs), acenaphthene, fluorene, phenanthrene, fluoranthene, pyrene and chrysene. Site characterization revealed multiple creosote sources. Areal subsurface bedrock DNAPL distribution, approximately 6500 ft², was much greater than previously reported. Total …

Examination of produced water from the Al-Hamada oilfield, Libya.
… phenol were within range, 0.1- 0.2 and compounds acenaphthene, indeno(1,2,3-cd)pyrene, benzo(b)fluoranthene of PAH were identified in the range between0.4-2ppm. These originate could be from biodegradation by existing bacteria, which generally changes the chemical composition and reduce the …

Photochemical Reaction Products of Polycyclic Aromatic Hydrocarbons Adsorbed at an Air-Water Interface
… themselves. Aqueous solutions of naphthalene, acenaphthene, 9<i>H</i>-fluorene, phenanthrene and pyrene were subjected to UVB light in a bulk-phase and a thin-film reactor to assess the identity of the formed photodegradation products. To aide in the challenging analysis of these mixtures, a …

Effects of the Desorption and Dissolution of Polycyclic Aromatic Hydrocarbons on Phytoremediation at a Creosote-Contaminated Site
… in this study were: naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, chrysene, and benzo(b)fluoranthene. The resulting data for the desorption equilibrium experiment revealed that rates of equilibrium were truly not instantaneous in the systems …

Lichens as biomonitors for atmospheric polycyclic aromatic hydrocarbons
… samples contained naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene and benzo[a]pyrene. It was seen that a full range of PAHs in terms of mass was extracted and identified, thus Parmotrema austrosinense (Zalhbr.) Hale was an appropriate choice of lichen species. The order of most …

Hydroxypropylmethylcellulose: A New Matrix for Solid-Surface Room-Temperature Phosphorimetry
… (PAHs): naphthalene, p-aminobenzoic acid, acenaphthene, phenanthrene, 2-naphthoic acid, 2-naphthol, salicylic acid, and triphenylene.Filter paper and HPMC substrates are inherently anisotropic, non-heterogeneous media. Since this deficiency cannot be addressed experimentally, a robust …

Sustainable catalysis using iron based catalysts for hydrofunctionalization of c=x (x = o, n) unsaturated bonds
… catalytic applications of BIAN (bis-(arylimino) acenaphthene) based iron complexes for the hydrosilylation of aldimines. Conversion of aldimines into amines is one of the most important chemical reactions in synthetic organic chemistry. Amines have been widely used for the production of bulk and …

Relationships Between Hybrid Poplar Tree Extractives and Ground Water Contamination at a Phytoremediation Site
… contaminant plume: naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, chrysene, and benzo(b)fluoranthene. The concentrations of these compounds steadily decreased over time, but the role the trees played in the remediation was unclear. In order to …

Design, Synthesis and Catalytic Evaluation of Mono- and Polynuclear Organometallic Materials as Hydroformylation Catalysts
… (DAD) ligands bearing either an ethyl or acenaphthene backbone were prepared. The alpha-diimine N,N-chelating ligands were synthesised via the Schiff base condensation reactions of 4-aminophenol with 1,2-ethanedione or acenapthenequinone, followed by sulfopropylation reactions with 1,3 …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… ranged from 0.983 for naphthalene to 0.999 for acenaphthene and acenaphthylene, which demonstrated the suitability of the method for routine monitoring of PAHs. The PASE procedure was firstly applied to the analysis of domestic outdoor fire (charcoal) air emission samples and naphthalene was the …
