Novel Adsorbents and Adsorption Methods for Pollutants Removal

Environmental challenges such as heavy metal contamination, radioactive waste, and organic pollutants threaten ecosystems and human health, driving research into innovative solutions. This reprint compiles 17 studies highlighting advancements in material development, pollution control, and waste valorization. A key focus is high-performance adsorbents—nanofibers, biochar composites, and functionalized polymers—that efficiently remove contaminants while balancing sustainability and cost. These materials offer high adsorption capacity, selectivity, and stability, supported by insights into contaminant transport mechanisms in multiphase systems. Radioactive waste management explores radiation-resistant adsorbents and radionuclide behavior in geological environments, aiding nuclear energy’s sustainable development. Another priority is converting waste into adsorbents for water treatment, merging resource recycling with pollution reduction. Studies also emphasize evaluating the ecological impacts of emerging materials to promote green technologies.  By integrating materials science, chemistry, and environmental engineering, these innovations advance sustainable pollution control strategies, addressing urgent environmental risks while fostering circular economies.
