Abstract:The changes of adsorption properties of uncalcined Al-pillared montmorillonite were studied. A soda-activated bentonite from Slovakia was reacted with polymeric hydroxoaluminium salt solutions. During storagein air at room temperature for three years, the basal spacing decreased by 0.15–0.2 nm; the specific surface area was reduced by 80% and the total pore volume by 40–60%. Adsorption experiments from ethanol-cyclohexane mixtures revealed the decreasing adsorption capacity and the increasing hydrophobicity. T… Show more
“…Since clay minerals are already known to be efficient sorbent of various pollutants [9][10][11][12][13][14][15][16][17][18], bentonite was also used for the Zn 2+ removal from aqueous solution [19,20].…”
