| Summary: | Water contamination with toxic pollutants such as heavy metals, oil spills, organic and inorganic dyes, pesticides, etc., causes severe environmental and human health pollution. Aerogels have gained increasing attention in recent years as promising adsorbents due to their outstanding properties. This paper critically evaluates the recent advancements in aerogel-based materials, highlighting their challenges, limitations, and practical applications in large-scale experiments. The influence of key parameters such as adsorbent dosage, solution pH, ionic strength, and temperature is also discussed. Integrating nanotechnology and advanced manufacturing methods, a new generation of high-performance adsorbents with increased sorption capacity and reusability could be developed. Additionally, pilot studies and field trials are highlighted in this review, showing aerogels’ practical and real-world applications. Although various gaps in the production process that limit aerogel implementation in the market still exist, the research progress in the field shows that novel aerogels could be used in real wastewater treatment in the future. This review underscores the need for future research to develop advanced aerogel-based materials using green and sustainable synthesis methods that can lead to full-scale application. |
