摘要

Crude oil spills have become a major environmental concern due to their frequent occurrence, especially in aquatic systems. Complex hydrocarbon combinations, such as diesel, gasoline, kerosene, and lubricating oil, are introduced by these spills. Each of these fractions has unique physicochemical characteristics that affect how they behave in the environment and how well they are removed. Because of its affordability, ease of use, and environmental friendliness, adsorption has become a popular remediation technique. This paper provides a detailed overview of the adsorption-based removal of crude oil fractions from water, with specific emphasis on diesel, gasoline, lubricating oil, and kerosene fractions of oil. Comparative data from several research show that adsorption capacities for natural, synthetic, and modified sorbents vary, with some materials reaching capacities of more than 100 g/g for specific fractions. The highest sorption values were obtained in diesel and lubricating oil among the fractions under study, especially when materials like magnetic nanocomposites and modified natural fibers were used. Additionally, the paper assesses the adsorption kinetics and mechanisms and offers a critical economic viewpoint, detailing the economic implications of sorbent usage, regeneration, and disposal. Furthermore, recommendations have been provided to serve as blueprints for future studies.
