Influence of kaolinite crystalline structure in the production of γ-Al2O3 by alkaline lixiviation

Adsorption of polyvinylimidazole onto kaolinite

“…Thermal treatment produces a maximum specific surface area of (22.72) m 2 g −1 at 600 • C. This result is generally in line with the literature [25][26][27][28]. The decrease in the specific surface area of kaolinite may be a result of the removal of most of the micropores and the folding of structure due to heating the sample [25][26][27][28]. Fig.…”

Equilibrium and kinetic studies for the sorption of 3-methoxybenzaldehyde on activated kaolinites

“…Selected calcination temperature in this study (873 K) is enough to ensure thermal activation. The studied temperature is generally in line with the reported literature [24,25,28,30]. Bhattacharyya and Sen Gupta [22] reported that further heating (calcination at ∼700 K) results in complete dehydroxylation of the aluminosilicate lattice, while retaining the Lewis acidity.…”
