Jordanian bentonite was activated by hydrochloric acid at room temperature. FTIR, XRD, TGA, and BET surface area analyses of the samples were carried out to examine the structure of bentonite before and after acid activation. It is found that the octahedral cations were removed, which altered the chemical composition of the bentonite.
The natural low silica bentonite from the deposit of Lopburi Thailand was provided by Thai Nippon chemical industry Co.,Ltd. To activate this low silica bentonite, 50 g raw bentonite was slowly added to 200 ml 0.1-1.0 M H 2SO 4 in 500 millilitres of round bottom flask equipped with condenser. The reaction was heated to 100 0C for 1 h, 6 h, and 12h,
