【 摘 要 】
Activated carbon is highly porous carbon which has been treated to increase its adsorption performance. Rice husk, due to its high cellulose and lignin content, can be used as source of carbons to produce activated carbon. This research aims to evaluate the effects of carbonization time and temperature on activated carbon production from rice husk and its application for lead (Pb) adsorption in car battery wastewater. In this research, dried rice husk was carbonized at 400-600 °C under constant nitrogen flow for 90 minutes to 150 minutes, followed by chemical treatment using HCl. Dried activated carbons was sieved to 100 meshes prior to application. Result indicated that maximum carbon yield of 49.33% was obtained at carbonization temperature of 500 °C and carbonization time of 150 minutes. The activated carbon contained 4.86% moisture, 30.04% ash, and 15.76% volatile matter. The adsorption capacity was found to be 0.56731mg/g with percentage removal 54.85%.
