Green Synthesis of Nano Composite based on Agro-Industrial waste and removal of pollutants from Waste Water

Ajay Singh, Aditi thapa

Abstract


India’s economy is largely dependent on Agriculture. A lot of agricultural waste is generated and most of the waste is burnt by the farmers in India, due to which economy is lost as well as environmental problem is created.In this study an effort has been made on green synthesis of nano-composites using agricultural waste like bagasee,rice husk and industrial waste like flyash material. Nano-technology is is being used in almost every field. Nano composites by using agri-residues like bagasse and industrial waste like fly-ash have been used in reduction of colour and other pollutants from waste water .Removal of colour and other pollutants is based on adsorption. Adsorption on the surface of nano-composites helps in the removable of heavy metal ions present in water. Flyash nano-particles were reinforced with reduced bagasse particles at about 100° C and characterised by using UV visible and SEM techniques. it was found that colour , BOD and COD could be adsorbed upto 70-80%. Keywords- Nano composite, bagasse, graphite, flyash, waste water ,characterisation techniques.
