Abstract: (2539 Views)
In this research synthesis procedure of activated carbon (AC) was optimized from pistachio waste in order to maximize the COD (Chemical Oxygen Demand) removal from nitro hydroxyl-terminated polybutadiene (nitro-HTPB) resin production unit wastewater through a batch system. For this purpose, Response Surface Methodology (RSM) was applied to optimizing the effective factors in AC synthesis condition preparation including impregnation ratio, carbonization temperature and activation time were investigated and The best conditions for activated carbon synthesis were obtained. The optimal conditions for impregnation ratio by phosphoric acid, carbonization temperature and activation time were 2.76, 524.34°C, and 38.04 min, respectively. It was revealed that, the as-synthesized AC (in accordance with the proposed condition set) is able to remove 90% of COD. The study shows that the “Freundlich isotherm” model was consistent with the results. Moreover, FT-IR and FESEM analyses were used to characterize bonds and surface morphology respectively.
