Separation of Sub-Micron Particles from Soils and Sediments without Mechanical Disturbance
Clays Dialysis Dispersion Mobility Particles Sediments Separation Size Soils Submicron Swelling
2011/12/1
Abstract: A method is described for the separation of the finest particles from soils and sediments without mechanical disturbance. Particles are separated through the induction of osmotic stress. Gen...
Gas Chromatographic Separation of Linear Hydrocarbons on Microporous Organo-Smectites
Gas chromatography Gas separation Hectorite Hydrocarbons Mesoporosity Microporosity Montmorillonite Organo-clays Smectites
2011/12/29
A series of organo-montmorillonites and organo-hectorites was prepared by complete ion-exchange from the pure sodium form of the parent smectites. The organic cations were tetramethylammonium, trimeth...
Iron Oxide-Clay Mineral Association in Brazilian Oxisols: A Magnetic Separation Study
Brazil Goethite Hematite Magnetic separation Oxisols
2011/12/30
Selected Brazilian Oxisols were sampled and submitted to high-gradient magnetic separation (HGMS) to study the iron oxide-clay mineral associations. The soils, derived from four different parent mater...
Palygorskite Separation from Dodecylammonium-Treated Clays
Dodecylammonium smectite Hydrophobic properties Mineral separation Palygorskite Sepiolite Smectite
2012/2/2
Three methods were investigated to separate palygorskite from mixtures of clay minerals in soils and sediments. The methods were based on the hydrophobic properties of a dodecylammonium-smectite compl...
