摘要：The widespread use of complexing agents ( e.g. , ethylenediaminetetraacetic acid, citrate) in industrial processes has resulted in the predominance of highly stable heavy metal complexes (HMCs) in wastewater. Conventional treatment technologies are rendered ineffective due to steric hindrance and strong coordination stability inherent to these complexes. To address this emerging challenge, diverse strategies for treating HMCs-contaminated wastewater have been developed. While advanced oxidation processes (AOPs) dominate current research, the adaptive optimization of conventional methods and the untapped potential of efficient reduction technologies remain significantly understudied. This review systematically integrates three technological frameworks, enhanced conventional processes, AOPs-based decomplexation, and high-efficiency reductive recovery, thereby bridging a critical knowledge gap. We comprehensively evaluate recent advances in HMCs treatment technologies, discussing their mechanisms, performanceenhancing strategies, and key limitations. Furthermore, we identify fundamental barriers to industrial translation and propose potential solutions, aiming to provide actionable guidance for managing complex heavy metal pollution.
