Abstract: Aniline, as a highly toxic, persistent, and chemically stable semi-volatile organic contaminant, presents a significant challenge in the efficient remediation of contaminated sites. This study provides a comprehensive review of the sources, characteristics, and detection methods of aniline contamination, and systematically discusses remediation strategies and techniques based on different concentration zones. These include physico-chemical synergistic remediation technologies for high-concentration areas, microbiological remediation methods for medium and low-concentration areas, and risk management measures for low-concentration zones. Furthermore, the study highlights the key issues currently faced in the field of remediation and offers an outlook on future trends, aiming to provide theoretical insights and technical support for the scientific and precise management of aniline-contaminated sites.
