A comparison study of removing Rhodamine B from waste water by functionalized natural and synthetic porous carbon. Proceedings of SLIIT International Conference on Advancements in Sciences & Humanities.https://rda.sliit.lk/handle/123456789/578PosterTextile industry discharge a huge amount of dye containing waste water which pollutes water, soil and also have adverse effect on human health, animal and plant. Approximately 10 - 15% of the synthetic dyes is released into the industrial waste, causing serious environmental problem, flora and fauna of aquatic ecosystem. It causes contamination of surface water, accumulation of toxic and carcinogenic substances in water. Rhodamine B is widely used in industrial purposes. However, the organic dyes will cause serious environmental and biological problems. Thus the removal of dye from water is a great challenge and a pressing task. Various porous carbon materials were applied to remove organic dye materials such as Rhodamine B from wastewater. Synthetic porous carbon was synthesized through the sol-gel method and carbonization process and naturally abundant waste materials like Rice husk and Coconut husk available at low cost were used as functionalized porous carbon materials which were obtained from slow pyrolysis process. According to the FT-IR, SEM and adsorption analysis adsorption capacities of these porous carbon materials were determined for Rhodamine B. HNO3 treated porous carbon materials were expressed positive results for absorptivity of RhB.enAdsorptionPorous carbonWaste materialsOther
