Palygorskite an overview ScienceDirect Topics

Palygorskite has a wide range of chemical architecture and the ratio of Al/Mg in the palygorskites is higher than sepiolites. This classification of clay mineral is available in fiber form with the ideal formula of Si 12 Mg 8 O 30 (OH) 4 (H 2 O) 4 _8H 2 O for sepiolite and Si 8 Mg 5 O 20 (OH) 2 (H 2 O) 4 _4H 2 O for palygorskite [178]. The

Adsorption of cetyltrimethyl ammonium bromide

Palygorskite (Plg; Warr, Reference Warr 2020) is a 2:1 clay mineral that possesses a moderately high structural charge due to the replacement of Al 3+ by Mg 2+ and Fe 2+ in the octahedral sheet. There are several types of active sites on the surface of Plg (Mu & Wang, Reference Mu and Wang 2016 ), which play important roles in the adsorption of
