A new method is proposed, based on a certain property of the spreading pressure, for determining the specific surface area of those solids which, when adsorbing gases isothermically, do so according to the type II isotherm of the Brunauer classification....
Adsorption isotherm type is a key factor in simulating chromatographic profiles. In this study, the adsorption isotherm type of pure bovine serum albumin (BSA) and immunoglobulin G (IgG) on hydrophobic interaction chromatography (HIC) media was found to shift from Freundlich to Langmuir with the in...
aThe explicit isotherm of L-shape, according to Giles et al.[28],indicated that there is no strong competition between the solvent and the dye to occupy the CTNTs active sites.Moreover,this type of isotherm implies Langmuir-type adsorption between MB and CTNTs molecules. L形状明确等温线,根据...

Our motivation is to correlate the structure of these three confined species to the fact that their adsorption isotherms are characterized by no step, one step, and two steps, respectively. From our detailed neutron diffraction investigation, we deduce that the adsorption isotherm steps are not ...
Here we describe how the Rigid Adsorbent Lattice Fluid is capable of a priori predictions both type I and type V adsorption behaviour in silicalite-1. The predictions are consistent with experimental observations for aliphatic (type I) and polar (type V) molecules in this hydrophobic material. ...
Adsorption and desorption phenomena can be simulated by using the Monte Carlo method. The following four cases were examined. 1. A Langmuir surface is placed under a constant concentration of adsorbate. 2. A Langmuir surface is placed in a system which contains a definite number of adsorbate mol...
H2TiO3 type adsorbent shows superior adsorptive capacity of Li+,with the value of 39.8 mg/g in LiOH solution.The adsorption process obeys pseudo-second-order rate equation,and the process can be seen as chemical adsorption...
The adsorbents (NMs), adsorption conditions (initial RE3+ concentration c0, adsorption time tad, adsorption temperature Tad and pH), adsorption characteristics (adsorption isotherm, kinetic model, adsorption thermodynamic, and adsorption mechanism) as well as adsorption capacity and efficiency of the ...
