摘要
采用常规搅拌混合和超声波震荡改性方法,制备了石墨烯分散液改性活性炭;通过比表面积、孔体积、孔径分布、碘吸附值等参数表征,考察了改性处理对活性炭性能的影响,研究了改性前后椰壳活性炭对甲醛的吸附特性。结果表明:通过超声波震荡改性活性炭的BET比表面积增加了25.14%,平均孔径下降,对甲醛的吸附量增加了13.60%,吸附速度有所增加。
Conventional mixing and ultrasonic vibration modification methods were adopted to modify coconut shell activated carbon by graphene dispersion. Through measuring the specific surface area,pore volume,iodine adsorption value and pore size distribution,the properties of activated carbon were investigated. The results showed that activated carbon BET increased 25. 14% which modified by ultrasonic oscillations, the average pore size decreased. The formaldehyde adsorption capacity increased 13. 60%,and the adsorption rate increased.
