Surface modification of magnetic nanoadsorbents using inorganic organic moieties for environmental remediation via green approach

Abstract

Environmental deterioration due to anthropogenic activities is a threat to sustainable, clean and green environment. Accumulation of hazardous chemicals in natural water streams adversely affects all the ecosystems. The hazards of aquatic toxins can be fixed by following two step approach. As a preliminary step, identification and detoxification of pollutants holds significant relevance towards complete treatment of polluted water. Hence, greater emphasis is needed towards developing approaches for the purpose of monitoring and removal of deleterious species which cause critical hazards. Magnetic nanomaterials are important in terms of green chemistry principles as these can be easily separated after the completion of reaction with the help of an external magnet, thereby limiting the generation of secondary pollution and thus fulfil the requirement for sustainable environment. Magnetic spinel nanoferrites have garnered remarkable research interest mainly due to their extraordinary characteristics such as chemical and thermal stability, non-toxicity, insolubility in solvents, high surface area and accessible surface active sites. Owing to the distinct properties of spinel nanoferrites, present work promotes the favourable surface modifications in nanoferrites for being utilized in the development of better water monitoring and treatment technologies that can be directly applied to real life problems. To summarize, the whole work is an effort to develop more efficient and economically viable magnetic nanomaterials with the added benefit of easy recovery. The aim was to alleviate the current societal problem of poor water quality and assured the availability of safe quality water via a sustainable and economic approach. newline
