Fenton oxidation remediation of petroleum-contaminated soil under high-quality development strategy: A review

Abstract

The permeation of petroleum pollutants severely disrupts the soil ecology and poses a threat to human health. Although research on the Fenton oxidation technology for the remediation of petroleum-contaminated soil is relatively mature, in-depth exploration is still lacking against the backdrop of high-quality development strategies. This study obtained a knowledge map through visualization and co-occurrence analysis of keywords, revealing the temporal and spatial distribution, knowledge structure, and hot research trends, providing a new perspective for understanding the dynamics of the research field. This article compares liquid- and solid-phase iron-catalyzed Fenton oxidation technologies and finds that the solid-phase technology performs better in efficiently removing pollutants, reducing treatment time, lowering costs, and being more environmentally friendly, thereby highlighting its potential as a high-quality development strategy. Additionally, we delve into the key factors affecting the effectiveness of Fenton oxidation, such as the dosage of H₂O₂, pH, temperature, catalyst selection, and soil organic matter content, providing a scientific basis for the optimization of the technology. Finally, this study predicts the application prospects of the Fenton system in soil remediation and proposes forward-looking development directions, aiming to guide future research and practice, thereby promoting the innovation and application of Fenton oxidation technology in environmental remediation.
