Oil pollution poses significant harm to both the ecological environment and human health. The primary sources of oil pollutants in soil are leaks that occur during the extraction, transportation, and production phases. In the face of the severe situation of global soil pollution, chemical oxidation technology has shown potential in the remediation of oil-contaminated soil. However, most current research on chemical oxidation technology remains in the laboratory stage, with limited discussion on its characteristics and application conditions in the actual treatment of oil-contaminated sites. To address this gap, this paper applies bibliometric methods to analyze the development trends of chemical oxidation technology and provides a comprehensive review from the perspective of its real-world applications in remediating oil-contaminated soil. It explores commonly used activators, enhancement measures, and key influencing factors of advanced oxidation processes, focusing particularly on those based on hydrogen peroxide and persulfate. The study highlights significant advantages, such as improving remediation efficiency, reducing treatment time, and compatibility with other remediation methods. Nevertheless, challenges remain, including soil acidification, limited pollutant targeting, and high operational costs. To address these issues, this paper proposes innovative directions such as the development of green and efficient activators, optimization of oxidant application strategies, and integration of chemical oxidation with other remediation technologies. These findings aim to establish a robust theoretical foundation and provide strong technical support for future chemical oxidation treatments of such soils. Through this research, we aspire to develop more scientific and effective strategies and methods for the remediation of oil-contaminated soil.
