以茄子秸秆、毛豆秸秆和橄榄核为原料制备活性炭,研究3种活性炭吸附正己烷的吸附穿透曲线、吸附动力学、吸附热和解吸率。结果表明:3种活性炭吸附正己烷穿透时间、吸附量、吸附热和解吸率均不同。3种活性炭吸附正己烷穿透行为均符合Logistic模型和Yoon-Nelson模型。3种活性炭对正己烷的吸附动力学行为均遵守准一级动力学方程、准二级动力学方程、Elovich动力学方程和班厄姆动力学方程。 Activated carbon was prepared from eggplant straw, soybean straw and olive kernel. The adsorption breakthrough kinetics, adsorption heat and desorption rate of n-hexane were investigated. The results showed that the adsorption time, amount of adsorption, adsorption heat and desorption rate of n-hexane were all different among the three activated carbons. The permeation of n-hexane by all three activated carbons was in accordance with Logistic model and Yoon-Nelson model. The adsorption kinetics of n-hexane on the three activated carbons are in accordance with quasi-first-order kinetic equation, quasi-second-order kinetic equation, Elovich kinetic equation and Bunge’s kinetic equation.
