Interactive and Adsorptive property of metal Nanoparticles

The existence of heavy metals from water sources is a serious environmental concern around the globe which is caused by an increased in industrial activities and urbanization expansion leading to detrimental state of the environment, including the pollution of land and water. Noxious heavy metals are the existing toxic contaminant to the watercourses and landfills through improper waste management from industries, inadequate farming habits, and metallurgical engineering and processing. Most of the heavy metals like lead and nickel are highly toxic, cancerous and could pose grave danger to life of human beings and aquatic organisms. Hence, finding efficient approaches to monitor and remove heavy metals from the environment is of great importance and has received prominent attention of scientists. The existing practices available to remove noxious heavy metal contamination have a potential set back; however, adsorption is one of the most suitable techniques for the removal of heavy metals.
Over the last decade, nanomaterials are providing lasting solutions in many fields like environment, food sector, and agricultural practices. Nanotechnology is an emerging field which is gaining prominent attention and various nanomaterials have been developed for removal of heavy metals from polluted water bodies such as metal and metal oxides nanoparticles which is due to their intrinsic features such as high surface area, high adsorption potential and excellent optical properties.
In this report, metal nanoparticles based on silver and gold nanoparticles are synthesised using the greener routes and the traditional routes, and characterized by Fourier Transform Infrared spectroscopy, UV-Visible spectroscopy, thermal Analysis, elemental analysis, SEM and TEM and powder X-ray diffraction. The metal nanoparticles were applied towards interaction and adsorption of heavy metals from aqueous solutions. Comparative studies were carried out on the interaction results and adsorption results of each metal nanoparticles synthesized.
