活性炭对苯及甲苯蒸汽吸附能力相关性的研究

Study on the Relativity between the Adsorptive Capacity of Activated Carbon to Benzene Vapour and That to Methylbenzene Vapour

以4种性质不同的粉状活性炭为对象，研究了它们对苯及甲苯蒸汽吸附能力。得知：活性炭对苯及甲苯蒸汽的吸附能力具有较好的相关性，可以用甲苯代替苯作吸附质来评价活性炭对有机溶剂蒸汽的吸附能力，并发现两者的相关性程度与活性炭的平均孔隙半径大小有密切关系。

The relativity between the adsorptive capacity of activated carbon to benzene vapour and that to methylbenzene vapour has ben followed from studying 4 kinds of powder activated carbon having different properties. Theresults show that the adsorptive capacity of activated carbon to benzene vapour is in close relationship with that tomethylbenzene vapour, the adsorptive capacity of activated carbon has a close relation to average pore radius of the activaed carbon,and methylbenzene can be used as a substitut for benzene to ditermine the adsorptive capacity of activated carbon to organic solvent vapour.
