Adsorption properties of metahalloysite

1971
The surface and porous properties of New Zealand metahalloysites, and the manner in which these properties are affected by chemical and physical treatments, have been studied by adsorption methods. The clay mineral surface has a considerable influence on the nature of the adsorption, process, polar water and ethyl chloride molecules giving rise to low ...

Adsorption properties of pillared clays

Protection of Metals and Physical Chemistry of Surfaces, 2014
The pillaring technique is used to synthesize materials with a microporous structure from native montmorillonite clays. It is established that the pillaring effect depends on the content of montmorillonite in the initial raw material. Adsorption properties of clays in respect to water vapors from gas media and organic dyes from aqueous solutions are ...

Adsorption and Physical Property Methods

1958
The analysis of the viscous fractions of petroleum by physical property correlations, and other short cut methods, is a very fascinating one. This approach is very different from the complete separation used by API Research Project 6 (19). The American Petroleum Inst.

Adsorption properties of lamellar silica

Russian Journal of Physical Chemistry A, 2007
Isotherms and heats of adsorption of water, n-heptane, trimethylamine, and methanol (at 303 K) vapors and isotherms of adsorption of nitrogen (at 77 K) on the lamellar silica prepared by removing metals from natural mineral vermiculate were measured.

Surface Properties and Gas Adsorption

2003
It is well known that alkali metal binary GICs adsorb gaseous species (H2, N2, Ar, CH4, etc.) physisorptively at low temperatures, where physisorbed gaseous molecules are accommodated in the interstitials of the alkali metal lattice within the graphitic galleries (Lagrange and Hérold, 1975; Lagrange et al., 1972, 1976; Watanabe et al., 1971, 1972, 1973)

Adsorption properties of porous silicophosphate

Russian Journal of Applied Chemistry, 2012
Isotherms of low-temperature physical adsorption-desorption of nitrogen for silicophosphate samples obtained at pH of the sol-gel transition varied from 5 to 9 in the presence of a template (cetylpyridinium chloride) were measured. The isotherms obtained were reconstructed in the form of t-graphs.

Adsorption-Desorption Properties of Bisphosphonates

Phosphorus, Sulfur, and Silicon and the Related Elements, 1999
Abstract Aminobisphosphonates have generated substantial interest recently for the treatment of bone diseases and as plant growth regulators, both alone and as a carrier for other drugs, because of the high affinity to the hydroxyapatite (HAP). We are investigating the drug delivery action of bisphosphonates for the treatment of osteoporosis and other ...

Adsorptive Properties of Biobased Adsorbents

Adsorption, 2005
Water and methanol vapor adsorption isotherms for native and modified potato starch were investigated. For obtaining the best fit for the experimental data several models based on the BET approach was evaluated. The hypothesis that water is adsorbed on the starch granules at the primary and secondary adsorption sites as well as a concept considering ...

Catalytic Activity and Adsorption Property

2010
Functions of zeolites as catalysts and adsorbents are related with the observed acidic properties. The turnover frequency and activation energy of alkane cracking depend on the ammonia desorption heat. Desorption heat of toluene on Na-zeolite is related with the ammonia adsorption heat of corresponding H-zeolite.
