摘要
用热重法研究了５ 种国产活性炭对水蒸汽和二硫化碳的吸附动力学行为．发现其动力学行为均遵循Ｂａｎｇｈａｍ 方程和Ｅｌｏｖｉｃｈ 方程所描述的规律，但Ｂａｎｇｈａｍ 方程更为优越．水蒸汽在活性炭上的平衡吸附量受温度影响非常严重，二硫化碳和水蒸汽在活性炭上的总平衡吸附量与单独吸附二硫化碳的量相比，因活性碳的种类不同而各异，这主要跟活性炭的孔结构及表面化学性质有关．
The kinetic behavior of adsorbing CS\-2 and CS\-2+H\-2O by five kinds of domestic activated carbon were studied by thermogravimetric technique.It was found that both Bangham and Elovich equations can be used to describe the adsorption kinetic behavior,but Bangham equation is more favorable.Temperature gave a remarkable effect on equilibrium adsorption of H\-2O.Because of the different pore structures and chemical properties on the surface of activated carbon,the total\|equilibrium adsorption of CS\-2+H\-2O varied from one activated carbon to another comparing to that of CS\-2.
