Nano Adsorbents in Wastewater Treatment: A New Paradigm in Wastewater Management

Abstract

Increasing water pollution has urged the need to elucidate more potent techniques for removing contaminants from wastewater 1 and groundwater. Numerous techniques or processes have been explored and designed for water purification. Amongst all other water/wastewater remediation techniques, nanotechnology has gained wider attention in water remediation via numerous mechanisms, such as the adsorption of heavy metals and the removal of pathogens. Nanoadsorbent materials have emerged as a promising solution for solving this crucial environmental issue. Their unique chemical and physical properties, such as higher ranking, quality, and status, promote their application compared to traditional adsorbents. Recent research studies have reported their promising potential in water treatment, including polymeric, carbon, tubezeolites, and metal nanosorbents. Hence, this review mainly aims to provide summarized data presenting all the beneficial aspects of nanosorbents in wastewater/water remediation.
