“…Many 23 adsorbents such as activated carbon (AC), biosorbents [10], 24 zeolites, nano-perfluorooctyl alumina [11], multiwalled carbon 25 nanotubes [12] and cellulose-based wastes [13] were reported to 26 decolorize wastewater. However, these adsorbents described 27 above suffer from low adsorption capacities or separation 28 inconvenience [14]. For example, AC is one of the most commonly 29 used adsorbent in adsorption treatment because of its highly 30 developed pore structure, large specific surface area, stable pollutants over a broad pH rang and be separated by magnetic 48 separation technology conveniently [19].…”

“…The characteristics of ES vary significantly in different regions due to the diverse nature of wastewater generated by various electroplating processes, which necessitates distinct treatment methods. Acid-base neutralization and coagulation-precipitation methods are commonly employed for the treatment of electroplating wastewater [15,16]. In cases where the wastewater contains metals such as Cr and Ni, an excess alkaline solution is utilized to induce a reaction and form hydroxide precipitates, followed by solid-liquid separation.…”

The disposal of electroplating sludge (ES) is a major challenge for the sustainable development of the electroplating industry. ESs have a significant environmental impact, occupying valuable land resources and incurring high treatment costs, which increases operational expenses for companies. Additionally, the high concentration of hazardous substances in ES poses a serious threat to both the environment and human health. Despite extensive scholarly research on the harmless treatment and resource utilization of ES, current technology and processes are still unable to fully harness its potential. This results in inefficient resource utilization and potential environmental hazards. This article analyzes the physicochemical properties of ES, discusses its ecological hazards, summarizes research progress in its treatment, and elaborates on methods such as solidification/stabilization, heat treatment, wet metallurgy, pyrometallurgy, biotechnology, and material utilization. It provides a comparative summary of different treatment processes while also discussing the challenges and future development directions for technologies aimed at effectively utilizing ES resources. The objective of this text is to provide useful information on how to address the issue of ES treatment and promote sustainable development in the electroplating industry.
