Effects of Exchanged Cation on the Microporosity of Montmorillonite
Exchanged Cation Interlayer Accessibility Microporosity Montmorillonite Surface Area
2011/12/22
Abstract: The micropore volumes of 2 montmorillonites (SAz-1 and SWy-1), each exchanged with Ca, Na, K, Cs and tetramethylammonium (TMA) ions, were calculated from the measured vapor adsorption data o...
Development of Microporosity in Clinochlore Upon Heating
Clinochlore Dehydroxylation Micropores
2011/12/29
The 乬modified chlorite structure乭 forms by the dehydroxylation of the interlayer octahedral sheet of magnesian chlorite at around 500亱C and results in a structure with a basal spacing near 27 侌 (Brind...
Microporosity in Montmorillonite from Nitrogen and Carbon Dioxide Sorption
Microporosity Montmorillonite Carbon Dioxide Sorption
2012/2/13
Nitrogen adsorption at 78亱K and carbon dioxide sorption at 195亱K on homoionic lithium, sodium, caesium, calcium, lanthanum and hexane diammonium saturated montmorillonites have been examined by means ...
The Effect of Heating in Vacuo on the Microporosity of Sepiolite
Vacuo Microporosity Sepiolite Effect of Heating
2012/2/15
The t-plot method has been applied to the results of nitrogen adsorption at 76°K on sepiolite first heated in vacuo at various temperatures. Heating sepiolite samples in vacuo at 427°K results in a la...
