Análise da eficiência de sorventes inorgânicos na remediação de derramamento de petróleo

Abstract

The oil industry, from the prospecting process to the moment of oil transportation, ends up generating some kind of environmental pollution. Referring specifically to maritime transport,it is observed that, when oil spills occur, the impacts on ecosystems can be terrible, with a threat to biodiversity, and society in the environmental, social and economic spheres. The present work comprehensively reviewed the progress made in oil spill remediation, especially of inorganic sorbents, for the research the Web of Science ScienceDirect (Elsevier), Scielo, Google Scholar, were used as scientific data sources in the period of November from 2022 to February 2023. The results obtained indicated that the sorbents with the highest absorption capacity are graphene/polypyrrole foam and polyethylene. The results also reached the conclusion that inorganic sorbents have desirable characteristics for the removal of oil spilled at sea, such as low cost, non-flammability, the volume of this material existing in the environment, among other properties, however, its large-scale production is still limited.
