Adsorption of 3-chloroaniline on potato skin in aqueous solution [PDF]
, 2016 The adsorption behaviour of aromatic amine 3-chloroaniline (3-CA) from aqueous solution on fresh potato skin was investigated. A series of batch experiments were conducted under different experimental conditions of contact time, 3-chloroaniline ...

Elastic heterogeneity governs asymmetric adsorption-desorption in a soft porous crystal [PDF]
, 2022 Metal--organic frameworks (MOFs), which possess a high degree of crystallinity and a large surface area with tunable inorganic nodes and organic linkers, exhibit high stimuli-responsiveness and molecular adsorption selectivity that enable various applications. The adsorption in MOFs changes the crystalline structure and elastic moduli.

Removal of basic yellow cationic dye by an aqueous dispersion of Moroccan stevensite [PDF]
, 2013 The aim of this study was to investigate the adsorption of basic yellow, a cationic dye, from aqueous solution by natural stevensite, with 104m2/g of specific surface area. The kinetics and the effects of several experimental parameters such as the pH of

Competitive Adsorption of a Two-Component Gas on a Deformable Adsorbent [PDF]
, 2013 We investigate the competitive adsorption of a two-component gas on the surface of an adsorbent whose adsorption properties vary in adsorption due to the adsorbent deformation. The essential difference of adsorption isotherms for a deformable adsorbent both from the classical Langmuir adsorption isotherms of a two-component gas and from the adsorption ...

Fermi level influence on the adsorption at semiconductor surfaces - ab initio simulations [PDF]
J. Appl. Phys. 114, 063507 (2013), 2013 Chemical adsorption of the species at semiconductor surfaces is analyzed showing the existence of the two contributions to adsorption energy: bond creation and charge transfer. It is shown that the energy of quantum surface states is affected by the electric field at the surface, nevertheless the potential contribution of electron and nuclei cancels ...

Photo-induced changes in the Langmuir adsorption constants of metal oxide layers in self-cleaning cation sensors. [PDF]
, 2012 For the first time, we have used a metal oxide-coated quartz crystal microbalance (QCM) to measure Cs+ adsorption onto illuminated and un-illuminated mesoporous TiO2 (m-TiO2) films by microgravimetric means in-situ. In the simplest case, such experiments

Chlorine adsorption on the Cu(111) surface [PDF]
, 1999 We investigate the adsorption of chlorine on the Cu(111) surface with full potential all-electron density functional calculations. Chlorine adsorption at the fcc hollow sites is slightly preferred over that at the hcp hollow. The adsorption geometry is in excellent agreement with electron diffraction and ion scattering data.

A Study of the Removal of Minor Amounts of HS from Natural Gas by Activated Carbon
Adsorption Science & Technology, 2002 Studies have been made of the removal of minor amounts of H 2 S from natural gas by activated carbon. The surface alkalinity of the carbon had a considerable effect on the H 2 S capacity, although this was not permanent.
