Abstract

The adsorption of organic pollutants on soil surfaces impedes their oxidative degradation efficiency within the soil medium. Understanding the distribution patterns of different petroleum hydrocarbon components on the soil medium surface can provide effective theoretical guidance for the technical regulation and efficiency improvement of in situ chemical oxidation (ISCO). Therefore, this study designed experiments involving interface diffusion, static desorption, and intensive desorption, and investigated adsorption patterns and component analysis. Fast-desorbing petroleum hydrocarbon components in on-site oil sludge were identified, including amines (e.g., 2-Phenylethylamine, 2,4,6-Trimethyl-m-phenylenediamine), acids (e.g., Benzoic acid, Octadecanoic acid). Relatively fast-desorbing components included phenols (e.g., Phenol), alcohols (e.g., Phenylmethanol, Dihydroxybenzene), ketones (e.g., Cyclohexa-2,5-dien-1-one, Cyclohepta-2,4,6-trien-1-one, and Pyrimidine-2,4,6(1H,3H,5H)-trione). Slow-desorbing components comprised carboxylic esters (e.g., Ethyl carboxylic acid ester), benzenoid olefins (e.g., 1'-(Cyclopenta-2,4-dien-1-yl)-1,4'-bipiperidine, 6-Allyl-1-methylnaphthalene). Finally, the remaining components in the soil were measured by extraction method as strongly adsorbed petroleum hydrocarbon components, including long straight-chain alkanes (e.g., Tetradecane, Hexadecane, Heptadecane, Octadecane, Icosane), and benzene esters (e.g., Dimethyl 5-methyl-1,3-benzene-dicarboxylate). It provides a theoretical basis for the accurate desorption of petroleum hydrocarbons from the soil surface.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
