Decreased Adsorption Capacity of CTAB in Montmorillonite by β-Cyclodextrin
Abstract:
To study the effect of β-cyclodextrin(β-CD) on the adsorptive action of cetyl trimethylammonium bromide(CTAB) in Na-montmorillonite,the inclusion activity between β-CD and CTAB was studied by measuring the surface tension of the solution at 303.15 K.The result shows that the host-guest inclusion complex's stoichiometric ratio is 1.53:1.By comparing the adsorption rate before and after inclusion,the mechanism that the adsorption capacity of CTAB in Na-montmorillonite is decreased by β-CD is studied.The adsorption capacity of CTAB in Na-montmorillonite decreased by about 75% after inclusion by β-CD.Simulated oil displacement experiment confirmed that the utilization ratio of CTAB has been increased significantly after CTAB having been included.
