Removal of Colour and Heavy Metals from Waste Water Using Nano-composite based on Rice Husk (Agro-Waste)

Ajay Singh, Priyanshi Kaushal

Abstract


Agriculture is prominent sector in India which affects largely our economy. A large quantity of agricultural waste is burnt by the farmers in India, which creates environmental problem as well as loss of economy. Nano-technology is very important emerging technology which is being used in almost every field. Nano composites by using agri-residues like bagasse and industrial waste like flyash have been used in this study for reduction of environmental water pollution.Carbon and its allotropes are known for their attraction towards ionic compounds. Hence this property helps in the removable of heavy metal ions present in water.(2)In this paper,the ability of rice husk (agricultural waste) to remove pollutants from waste wateris used as an adsorbent for the synthesis of nanocomposite. Rice husk which is available in huge quantity in India, is the primary component for this experiment. For the construction of nanocomposite several experimental conditions were conducted with the help of rice husk ash. The rice husk was used after its pre-treatment with NaOH. Effect of parameters, namely pH and COD has been studied. With the use of glycerol, cellulose and RHA (rice husk ash) the nanocomposite was synthesized.
