Synthesis of Agro waste Nano Composites Using coconut and rice husk for adsorption of chromium ions

Abstract

As India is the second largest country producing wheat and rice in the world resulting in production of large amount of residue. Agro Residue burning has become biggest environmental problem in India causing air pollution, global warming as well as health issues. As nanotechnology is most fascinated area in every field including pharma, food and cosmetics so scientists are trying to utilize these agro residues in the field of nanotechnology. In this study, agro residues specifically coconut husk, rice husk and rice straw were subjected to alkaline and bleaching treatment which further resulted in nano cellulose-composites which have application in heavy metal adsorptions. In this study nano-composite of coconut and rice husk has capacity of about 97-100% absorption of chromium heavy metal ions.
