The Problem of Expressing the Specific Surface Areas of Clay Fractions
Density Fe and Ti oxides Magnetic and non-magnetic fractions Specific surface area
2011/12/28
Estimations of the external specific surface areas (S.S.A.) by the N2-BET method of clay separates that were further fractionated by the high gradient magnetic separation technique revealed that the m...
Effects of Iron Oxidation State on the Specific Surface Area of Nontronite
Ethylene glycol-monoethyl ether Iron Nontronite Oxidation Specific surface area
2012/1/9
The effect of Fe oxidation state on the specific surface area, Sm, of nontronite was studied using the <2-祄, Na+-saturated fraction of the SWa-1 and Garfield nontronite reference clays. The reduction ...
Measurement of the Specific Surface Area of Clays by Internal Reflectance Spectroscopy
Ethylene glycol monoethyl ether Infrared spectroscopy Internal reflectance spectroscopy Molar absorptivity Montmorillonite Surface area
2012/2/2
The specific surface area, S, of a clay is commonly measured by the adsorption of ethylene glycol monoethyl ether (EGME); however, this method can be tedious and time consuming, especially if the clay...
