NMR detects molecular interactions of graphene with aromatic and aliphatic hydrocarbons in water

The Toxicity and Potential Dangers of Aliphatic and Aromatic Hydrocarbons *

The aliphatic hydrocarbons play an increasing role as solvents in different industries and the appraisal of the hazards connected with their use offers considerable difficulties because most of these solvents represent mixtures, sometimes of heterogeneous nature, and because their composition is frequently only incompletely known. In order to evaluate the potential dangers of such mixtures it i...

Selection of ionic liquids for the extraction of aromatic hydrocarbons from aromatic/aliphatic mixtures

The separation of aromatic hydrocarbons (benzene, toluene, ethyl benzene and xylenes) from C4 to C10 aliphatic hydrocarbon mixtures is challenging since these hydrocarbons have boiling points in a close range and several combinations form azeotropes. In this work, we investigated the separation of toluene from heptane by extraction with ionic liquids. Several ionic liquids are suitable for extr...

Bioavailability of Aromatic Hydrocarbons and Their Interactions with Natural Organic Matter: Linking Molecular- and Microbial-Scale Interactions

Accurately measuring the bioavailability of organic contaminants associated with complex environmental matrices is necessary for assessing contaminant risk, as well as for evaluating the effectiveness of proposed and in-place remediation strategies. Due to its importance, the bioavailability of organic contaminants associated with soils and sediments has been widely examined at the macroscopic ...

Aliphatic and Aromatic Hydrocarbons in Tropical Recent Sediments of Campos dos Goytacazes, RJ, Brazil

Foram estudados sedimentos recentes dos rios Imbé, Urubu e Ururaí e da Lagoa de Cima, localizados no município de Campos dos Goytacazes, Rio de Janeiro. As frações dos hidrocarbonetos alifáticos e aromáticos foram analisadas por CG-DIC e CG-EM com o objetivo de se verificar o grau de contaminação por atividades antropogênicas ou contribuições biogênicas. A concentração total dos hidrocarbonetos...
