摘要
本文利用氧化铜对两种不同活性炭进行改性研究,通过对其表面的官能团比、微观结构、表面积和其吸附脱附能力表征,结果表明:通过改性可以增大活性炭的微孔容积,提高活性炭的比表面积;改性椰壳活性炭的比表面积及吸附量均大于改性杏仁壳活性炭。
In this paper,copper oxide was used to modify two kinds of activated carbon.Through the characterization of functional group ratio,microstructure,surface area and its adsorption and desorption capacity,the results showed that the micropore volume of activated carbon could be increased and the specific surface area of activated carbon could be increased;the specific surface area and adsorption capacity of modified coconut shell activated carbon were greater than that of almond shell activated carbon.
