Critical discussion of the use of adsorption measurements from the liquid phase for surface area estimation

Hydrogenation of Benzaldehyde over Palladium Intercalated Bentonite Catalysts: Kinetic Studies

“…1). The molar reduced surface excess amount n 1 r(n) is related to the actual amount present in the interlamellar space by Ostwald-de-Izaguirre equation [20].…”

Cadmium Ion Adsorption Controls the Growth of CdS Nanoparticles on Layered Montmorillonite and Calumit Surfaces

“…CdS nanocomposites Determination of the adsorption excess isotherm, n 1 (n) ϭ f( x 1 ), as reported previously (14 -16), led to the values n 1 s ϭ 4.75 mmol/g, n 2 s ϭ 3.59 mmol/g, and n 1,0 s ϭ 11.0 mmol/g for HPD-M. For DBS-C, n 1 s ϭ 1.05 mmol/g, n 2 s ϭ 0.91 mmol/g, and n 1,0 s ϭ 2.71 mmol/g, using the Schay-Nagy extrapolation method (15), or by the Everett-Schay function (13). These values, in turn, permitted the calculation of the volume of the adsorption layer (i.e., the volume of the nanoreactors, V s ) to be 0.664 cm 3 /g for HPD-M and 0.164 cm 3 /g for DBS-C.…”

“…The adsorption isotherms of Cd 2ϩ ions onto DBS-C ( The volume of the adsorption layer (V s ) on a given HDP-M or DBS-C surface can be calculated by the adsorption space filling model (13)(14)(15),…”

Adsorption from Ternary Liquid Mixtures on Partially Dehydroxylated Silica Gel

“…Most difficult to interpret are the data of (sample SiO 2 /600), and 800ЊC (sample SiO 2 /800). The adsorption from liquid mixtures due to the competitive char-physical characterization of silica samples including specific acter of the process in addition to the chemical heterogeneity surface area a s , mean pore radius R p , and pore volume V p of the solid surface (see, e.g., [1][2][3][4][5][6]. The prevailing number was performed by using the adsorption/desorption data at of papers concern the investigations of adsorption from bi-0195ЊC.…”

“…For each composition two flasks contially dehydroxylated are good model materials for these taining the same mixture were prepared. A known quantity of silica (about 4 g) was added to the weighed amount of 1 To whom correspondence should be addressed. consisting of the mixture and adsorbent was shaken for 8 mation concerning investigated adsorbents derived from these data.…”
