摘要：
以商业木质活性炭为原料,通过Fe(NO3)3催化改性结合二次活化的方法得到富含2～5 nm中孔的适于吸附二恶英的活性炭.研究Fe(NO3)3与活性炭的质量浸渍比、改性温度、改性时间对活性炭孔结构变化的影响.结果表明,当改性温度为900 ℃,CO2体积流速为0.5 L/min, 质量浸渍比为1%时催化效果最好,改性2 h后得到的活性炭2～5 nm中孔孔容达到0.37 cm3/g,占总孔容的62.1%.利用浙江大学研制的二恶英发生源系统搭建吸附实验台,吸附数据显示改性后活性炭吸附二恶英的能力明显增强,在同等条件下可以将二恶英毒性当量的移除效率从43.0%增加到61.4%.
Abstract:
Commercial wood based activated carbon was modified to prepare specified mesoporous activated carbon by Fe(NO3)3 impregnation coupled with CO2 activation in order to increase adsorption capacity of PCDD/Fs. Process variables such as impregnation ratio, activation temperature and activation time were considered. Results show that when the impregnation ratio is 1%, the temperature is 900 ℃, the rate of CO2 is 0.5 L/min and the activation is 2 hours, the mesopore (2 5 nm) volume of modified activated carbon can reach 0.37 cm3/g and account for 62.1% of the total pore volume. An adsorption generator was applied for the adsorption of PCDD/Fs. Results show that the modified one can have a larger adsorption capacity of PCDD/Fs compared to the original activated carbon. Its toxic equivalent quantity (TEQ) removal efficiency can reach 61.4%, while the original activated carbon is only 43.0%.
