Abstract:
This work explores the potential of nanostructured materials for advanced water treatment, focusing on their unique nanoscale properties, including high surface area, tunable porosity, and enhanced reactivity, Metal nanoparticles, carbon-based nanostructures, polymeric nanofibers, and hybrid composites are examined for their ability to remove heavy metals, organic pollutants, and pathogens through adsorption, photocatalvsis, and antimicrobial mechanisms, While these materials ofer significant improvements over conventional methods, challenges such as cost, scalability, environmental impact, and nanoparticle toxicity must be addressed. The presentation also highlights emerging trends in multifunctional, and sustainable nanomaterials, aiming to provide safe, efficient, and scalable solutions for global water purification needs.
Speaker Biography:
Prof. Zikhona Tetana (PhD, chemistry) is an Associate Professor at the University of South Africa in the Institute for Nanotechnology and Water Sustainability, contributing to the Nanostructured Materials Thematic Area.
