Application of Advanced Materials and Technologies in the Separation and Adsorption

This Reprint presents a curated collection of cutting-edge research on the transformative roles of advanced materials and technologies in separation and adsorption processes. The volume explores novel materials and innovative techniques designed to enhance the capture and isolation of target compounds across industrial and environmental applications. The chapters cover a wide spectrum of topics, from advanced porous carbons and metal-modified bio-adsorbents to smart polymer composites and catalytic textiles. Key studies include the use of nitrogen-doped porous carbon derived from biomass for efficient CH4/N2 separation, magnesium-loaded bamboo powder and nano-crushed oyster shells for nitrate ion adsorption, and selective VOC capture on thermally modified activated carbon under humid conditions. Additional contributions address the removal of condensable particulate matter from coal-fired flue gas via phase-change technology and the degradation of organic dyes using a copper–chitosan-modified magnetic textile with peroxidase-like activity. The Reprint also features a comprehensive review of hydrogel applications in wastewater purification, highlighting their high porosity, tunable surface chemistry, and pollutant removal mechanisms. By bridging materials science, chemical engineering, and environmental technology, this Reprint serves as an essential reference for researchers, engineers, and graduate students seeking to advance separation science and develop high-performance, sustainable solutions for pollution control and resource recovery.
