Influence of Heat Treatment on the Pore and Adsorption Characteristics of Sodium Doped Alumina Pillared Bentonite

摘要

Various amounts of Na~+ ions were exchanged into alumina pillared bentonite (Al-PILB) sample, by controlling the pH of the dispersion of Al-PILB and sodium chloride solution. The Na~+ doped pillared clays were calcined at elevated temperatures and adsorption ofnitrogen at -196 dge C, cyclohexane and water at ambient temperature (21±1 deg C) by the calcined samples were conducted. The results revealed a wide size distribution of the micropors in the pillared clay.
