The article "Green Adsorbents for Environmental Remediation: Synthesis Methods, Ecotoxicity, and Reusability Prospects" by Yanju Liu, Bhabananda Biswas, Masud Hassan, and Ravi Naidu reviews the development and application of sustainable adsorbent materials for environmental remediation. The authors highlight the importance of "green" or "eco-friendly" sorbent materials, which are derived from renewable or recycled resources, have minimal toxic effects, and are synthesized with low chemical or energy footprints. These materials are designed to be highly reusable and do not contribute to additional waste or contamination. The review covers various aspects of green adsorbents, including their synthesis techniques, ecotoxicity, and reusability. It emphasizes the use of low-cost or waste materials to produce sorbent materials for immobilizing contaminants from soil and water systems. The regeneration possibilities of adsorbents are evaluated to assess their cost-effectiveness and long-term environmental impact. Key topics discussed include: 1. **Synthesis Techniques**: Chemical synthesis, physical modification, and bio-based approaches are evaluated for their efficiency in improving surface characteristics and adsorption capacity. 2. **Ecotoxicity**: The potential risks to biotic and abiotic ecosystems are assessed, considering the chemical composition, physical properties, and potential leaching of toxic substances. 3. **Reusability and Regeneration**: Techniques for desorption and regeneration are discussed, along with their impact on the sorbent's performance and sustainability. The article also provides insights for researchers and practitioners interested in developing and applying green adsorbents, including bio-based carbon, char, and fibrous materials for soil and water remediation. It highlights the importance of sustainable development goals and the circular economy in the context of environmental remediation.The article "Green Adsorbents for Environmental Remediation: Synthesis Methods, Ecotoxicity, and Reusability Prospects" by Yanju Liu, Bhabananda Biswas, Masud Hassan, and Ravi Naidu reviews the development and application of sustainable adsorbent materials for environmental remediation.
