Adsorption properties of aluminum oxide modified with Co and CoO particles
Adsorption properties of γ-Al 2 O 3 modified with Co (5 and 10 wt %) and Co (5 wt %) species are investigated by dynamic adsorption. N -hexane, n -heptane, n -octane, benzene, toluene, ethylbenzene, chloroform, and diethyl ether were used as test adsorbates. Adsorption isotherms were measured, and i...
