dc.description.abstract Clean water is a basic need of all organisms including humans. However, due to industrial and human activities of human, there is release of toxic pollutants in unprecedented amounts into the water sources. One such toxic pollutant is hexavalent chromium. Hexavalent chromium has been found to cause many ailments including cancer. Conventional methods of removal of hexavalent chromium have various drawbacks such as use of toxic chemicals, generation of toxic by-products. Biosorption is a method which is eco-friendly, does not involve the use of toxic chemicals. Lignocellulosic plant materials are cheap, available in plenty amount, biodegradable, eco-friendly and have been found to be good material for biosorption of toxic pollutants including hexavalent chromium.In the present work, we have explored three different lignocellulosic plant materials namely Pinus kesiya, Senna siamea and Phanera vahlii and activated carbon prepared from these materials for the abatement of hexavalent chromium from synthetic waste solutions. All materials were characterized using FESEM, EDX, FTIR, BET and TGA. Parameters influencing adsorption process such as pH, biosorbent dose, contact time, temperature and initial metal concentration were optimized. en_US
