This gives rise to a simple multiparametric isotherm based on the grand canonical ensemble statistics, whose functional form is a ratio of two polynomial functions. The parameters are interpreted as adsorption equilibrium constants. A simple recurrence relation for the equilibrium constants is proposed ...
A new numerical procedure, based on the simulated annealing algorithm (SA), for optimizing the parameters of a new recently developed gamma-type adsorption isotherm equation is proposed. This procedure is verified for three modeled adsorption isotherms assuming some arbitrarily chosen shapes of the pore...
The corresponding adsorption isotherm has been registered at room temperature due to the good solubility of the phase. In comparison with the traditional HDS catalysts, this new system shows the following relevant aspects: (a) the activity for the HDS of thiophene is similar in both cases, ...
aFollowing the classification of IUPAC, all the nitrogen adsorption–desorption isotherms are considered to be a typical type IV isotherm, which suggests that raw diatomite and ferrihydrite-modified diatomite are a mesoporous material. 在IUPAC的分类以后,所有氮气吸附解吸附作用等温线认为一个典型的类型IV等...
Both inhibitors seemed to obey the Langmuir adsorption isotherm equation. Dithizone was chemisorbed, whereas thiosemicarbazide was physisorbed on the surface of type 304 stainless steel. Dithizone acted as a mixed inhibitor, while thiosemicarbazide was cathodic in nature....
A Freundlich adsorption isotherm is suitable for the acidic and basic regions, while a Langmuir adsorption isotherm is suitable for the region of pH 5–8 where a maximum adsorption has been achieved. In aqueous solutions containing organic solvents, the adsorption was strongest with aqueous solutions...

The porosity of CuCo2O4 MTs and CuCo2O4 microflowers (CuCo2O4 MFs, 170 °C) is investigated by N2 adsorption-desorption measurements. It is observed from Fig. 6a and c that each curve possesses a H3 loop and ascribes to the type IV isotherm. Such feature demonstrates a mesoporous structur...
The experimental adsorption isotherm plot shows that the BEA zeolite/Fe3O4 composite can remove sulfadiazine through adsorption, and the adsorption was found to well fit to linear Freundlich isotherm model. Highlights Effect of dry-gel conversion synthesis conditions for magnetic BEA zeolite composites ...
Adsorption and desorption on BET surfaces with finite allowable layers can be simulated by using the Monte Carlo method. For the following two cases, the numbers of adsorbed molecules have been calculated as a function of time. 1. A simple BET surface is placed under a constant concentration of...
