Highly Porous Carbon Nanoparticles From Recycled Waste Papers for Water Filtration Applications

 

Throughout the world people are facing acute water problems including access to adequate clean drinking water and sanitation. About 3.4 million people, mostly children, die annually from water-related diseases. Most of these illnesses and deaths can be prevented through simple, inexpensive water treatment measures. Global warming also deteriorating this scenario pitilessly which eventually trigger rigorous research attempts to elicit robust methods of water purification in a cost effective way. As a consequence, in this study, highly porous carbon nanoparticles (HP-CNPs) were synthesized through one step pyrolysis of waste papers and activation process using HCl. The synthesized HP-CNPs was characterized by X-ray Diffraction (XRD), Raman Spectroscopy, BET surface area analyzer, Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). Preliminary experiments revealed the conversion of the dominant cellulosic component in waste papers to graphitic carbon from isothermal reactions of waste papers held at 1000 0C for 2 hours through Raman microscopy and X-ray diffraction analysis respectively. BET surface area analysis confirmed the improvement of surface area (1.372 m2/g before activation and 261.520 m2/g after activation) and pore size distribution of as prepared ash from self-pressurized pyrolysis process after HCl activation. Scanning electron microscopic analysis revealed the ultrahigh porous carbon particles from recycled waste papers. The investigation of water treatment using the prepared porous carbon particles is in progress.
