CARBON NANO PARTICLES: A POTENTIAL PLASMONIC MATERIAL FOR WATER DISINFECTION

In last two decades nanotechnology is emerged as a potential solution for various energy and environment challenges. Nowadays, nano materials based on polymer, inorganic materials, bio-materials extensively used for the detection and removal chemical and biological substances. The presence of hazardous pollutants and germs in water can also be effectively treated by using nanomaterials. The goal of this study was to synthesize carbon nanoparticles (CNPs) based on the waste materials which provides promising heating efficiency required for solar disinfection. Total 12 number of materials were prepared by using precursor of different agricultural and household wastes. All synthesized materials were evaluated for water heating efficiency in natural sunlight. The highest water heating efficiency was achieved with the CNPs prepared from the precursor of P-1 vegetable wastes. This promising material was also studied for the water disinfection application which accomplishes zero E-coli (6 log reduction) within span of 90 minutes.
