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...
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 ...
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...
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...
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...
The surface area of the samples was calculated from the appropriate isotherm of nitrogen adsorption, according to the Brunauer, Emmett, Teller method. The total pore volume (VT) was determined on the basis of the volume of adsorbed nitrogen at the relative pressure p/p0 = 0.99, which...
A parameter c which is closely related to the constant c of a BET isotherm is found to characterize the distinctness of the layered structure of an adsorbed phase. Excluding the last two types, the empirical BDDT classification of adsorption isotherms is explained in terms of the distinctness of...

Nitrate adsorption isotherms were drawn in a large concentration range [0.8–24.2 mmol.L−1] and fitted with Langmuir isotherm model. The maximum nitrate removal capacity (1338 mmol.Kg−1/83 mg.g−1) was obtained for SMZNS material. This value is the highest ever observed for...
