Adsorption of crude oil on anhydrous and hydrophobized vermiculite

Thermal properties of sodium-exchanged palabora vermiculite

“…The exfoliated "vermiculite" is of industrial interest because it is incombustible and lightweight and shows excellent absorption and thermal insulation properties (Wada, 1973b, Schoeman, 1989Tomanec et al, 1997;Obut and Girgin, 2002;Bergaya et al, 2006). It is used as lightweight aggregate in concretes and plasters (Wada, 1973b;da Silva et al, 2003); as absorbent in water purification, and for controlled release of fertilizers and pesticides (Schoeman, 1989).…”

Removal of cadmium, zinc, manganese and chromium cations from aqueous solution by a clay mineral

“…Vermiculite was the clay mineral chosen for heavy metal adsorption. It is classified as 2:1 type and it has been explored with the aim of evaluating structural changes, adsorptive, catalytic and electrochemical properties [12][13][14][15][16]. Several works have applied vermiculite as ion exchanger for hazardous cations [17][18][19][20][21].…”

Organic intercalation of structure modified vermiculite

“…The structural unit of vermiculite is composed of two opposing tetrahedral [SiO4] layers and one [MgO6] and/or [FeO6] octahedral layer in between, which is about 1 nm in thickness and stacks periodically in c axis to form the vermiculite crystal [2,3]. The interlayer space of vermiculite, characterized by ion exchange, adsorption etc., provides a good place for chemical reactions [4][5]. Organic or inorganic species can be introduced into vermiculite interlayer space by physicochemical method, such as ion exchange, adsorption, pillaring and intercalation, resulting in the change of vermiculite properties.…”
