Industrialisation of Indian subcontinent in the last decade leads to contamination of our soil and water with oil and dyes. So surface water get contaminated and not able to use for drinking. Science and Technology now focused on sustainable and eco friendly biodegradable materials for adsorbing these contaminants. Over the last decade, so many research groups are engaged to find out a concrete solution for this problem. Results have been reported by researchers about preparation, processing and fabrication of cellulose nano fibre aerogel. The fascinating properties of this material include high surface area, strength, aspect ratio and cost effective in nature suggests a huge potential material for water purification. However due to hydrophilicity of cellulose, it was not able to use in water treatment applications. We extracted cellulose nano fibre from waste biomass of newspaper and freeze dried to obtain aerogel. Surface modifications were done on cellulose aerogel viz. silination of aerogel using trimethoxy silane. This method was induced hydrophobicity in cellulose nano fibre aerogel and thereby can be efficiently used for water purification. This aerogel are low cost, elastic, ultra light, reusable and eco friendly. Adsorbed dye in cellulose aerogel can be easily reused by simple mechanical squeezing. So our work lay foundation for development of biodegradable, eco friendly and sustainable oil, dye, chemical pollutant and bacteria removal applications.
