Preparations of organobentonite using nonionic surfactants.

摘要: Due to hydrophilic environment at its surface, natural bentonite is an ineffective sorbent for nonpolar nonionic organic compounds in water even though it has high surface area. The properties of can be greatly modified by simple ion-exchange reactions with large cations (cationic surfactants) and this organobentonite highly effective removing from water. Cationic surfactant derived organobentonites have been investigated extensively a wide variety environmental applications. In study, the preparation using surfactants first time. Results indicate that intercalates into interlamellar space may demonstrate higher sorption capacity than cationic surfactant. It possible create interlayer spacing carbon content use suitable balance between hydrocarbon ethylene oxide chain lengths. addition, are more chemically stable organobentonites.
