Magnetic Nanocomposites for Removal of Arsenic from Water
Arsenic significantly impacts human health and the environment and its removal from wastewater is still difficult. Magnetic nanoparticles have come to light as a viable arsenic remediation technique, providing a fresh and long-lasting water purification method. This study investigates the use of magnetic nanoparticles to remove arsenic by concentrating on their adsorption mechanism, kinetics, potential for adsorption, recovery, and promising use of this method in the future. Due to the extensive surface area and variable surface chemistry of magnetic nanoparticles, they can effectively adsorb arsenic from water sources. Because their magnetic properties simplify separation and regeneration, they may be used again with little to no efficiency loss. As a result, they reduce trash output by providing an ecologically acceptable alternative to traditional adsorbents. The present study also examines the kinetics and adsorption process of magnetic nanoparticles, emphasising their improved selectivity and capacity for adsorption. Due to these characteristics, the authors were able to successfully remove arsenic from wastewater, resulting in better water quality and decreased health hazards after exposure to arsenic. Additionally, the potential applications of magnetic nanoparticles in removing arsenic have been highlighted. It is envisaged that advances in material science and nanotechnology will create unique magnetic nanoparticles with even better performance. Combining hybrid materials and surface alterations can increase their effectiveness in wastewater treatment settings.
