原始语种摘要: Ten samples of activated carbon were successfully prepared by carbonization and activation of fluted pumpkin seed shell. Thermal activation was achieved at 300°C, 400°C, 500°C, 600°C and 700°C, while chemical activation was achieved by first impregnating the prepared raw material with activating reagents, and then carbonization at 500°C. Characteristics of the activated carbons were determined using standard methods. Increasing the activation temperature from 300°C to 700°C showed improved characteristics and optimum temperature for production of activated carbon was obtained at 500°C after 2 hours. The iodine values for physically prepared carbons were generally lower, compared to chemically prepared carbons. Phosphate removal efficiency and rates of phosphate removal were satisfactory...
