Synthesis of Carbon from Rice Groats at Various Pyrolysis Temperatures and Its Application for the Recovery of Chromium Wastewater from the Tannery Industry

The research on synthesis of carbon from rice groats at various pyrolysis temperatures and its application for the recovery chromium wastewater tannery industry by varying 300, 400, 500 °C. results are analyzed in form determination yield, water content, ash iodine number. best condition with quality requirement is a temperature °C 760 mg.g-1 (iodine number). Adsorption kinetics was also carried out to determine adsorption ions wastewater. model corresponds pseudo-second-order R2 0.9857, k2 0.0093 g.mg-1.min-1, qe 28.5714 mg.g-1.
