Prediction of CO2/N2 Selectivity in Porous Carbons from N2 Adsorption Isotherm at 77 K via Convolutional Neural Networks.

Angewandte Chemie, 2020
Porous carbons are an important class of porous materials with many applications including gas separation, while N 2 adsorption isotherm at 77 K is the most widely used approach to characterize porosity. Conventionally, textual properties such as surface

Adsorption capacity, isotherm, kinetic, and thermodynamic studies on adsorption behavior of malachite green onto natural red clay

Environmental Progress & Sustainable Energy, 2020
The adsorption of Malachite Green onto natural red clay by batch‐adsorption technique is investigated. The effects of initial dye concentration, amount of adsorbent, adsorption time, pH, and temperature are examined.

Adsorption isotherms-microscopic modelling

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1977
Abstract A lattice formalism using “spin variables” is employed to analyse multi-state models for the adsorption of neutral dipoles. In particular, a spin-1/2 (two-state) model incorporating permanent and induced dipole moments of the solvent and the organic adsorbate, substrate interactions, and discreteness of charge effects is analysed.

Adsorption isotherms and thermal fluctuations

Physical Review B, 1996
The influence of thermal fluctuations on adsorption isotherms is calculated within the context of a selfconsistent mean-field theory, and it is found that such fluctuations cannot be neglected in the analysis of adsorption data. This result arises from our observation that substrate-induced hindrance of thermal fluctuations can significantly alter the ...

General purpose adsorption isotherms

Environmental Science & Technology, 1986
The fitting of adsorption isotherm equations to experimental data is often an important aspect of data analysis. If the Langmuir and Freundlich isotherms are used, then consideration must be given to the proper weighting of the observations. Preferably nonlinear regression (nonlinear least squares) should be used since this enables these isotherms to ...

Adsorption isotherms—A critique

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1973
Summary The possibility or the impossibility of separating the particle and the electrode interactions is discussed in a wider context of the effects due to any two interaction potentials on the equation of state. The involved nature of the pressure dependence on two individually definable forces is illustrated through the Percus Yevick results for ...

Quantitative Characterization of Adsorption Isotherms Using Isothermal Microcalorimetry

Journal of Pharmaceutical Sciences, 1996
The integral heat of adsorption of water vapor on sodium benzoate samples was determined at various partial vapor pressures using a heat conduction microcalorimeter. An equation is presented to describe the calorimetric integral heat response (mJ/g of solid) as a function of relative humidity.
