Mixed ad/desorption kinetics unraveled with the equilibrium adsorption isotherm
(Elsevier Science, 2019-09)
Predicting ad/desorption rates at solid/solution interfaces is important for environmental and industrial processes. For non-porous surfaces the adsorption process can be divided in film diffusion and surface reactions. ...
Uranium removal by chitosan impregnated with magnetite nanoparticles: adsorption and desorption
(Sao Paulo: ABEN, 2009, 2014)
Anisotropy of crystallite growth during sintering of SnO2 xerogels
(1996-12-01)
The crytallite and pore-size evolution during isothermal sintering (400 ≤ T ≤ 700°C) of SnO2 xerogels was studied by X-ray line broadening and nitrogen adsorption-desorption isotherms. The experimental results show a strong ...

On the computer simulations of carbon nanoparticles porosity: statistical mechanics model for CO2 and N2 adsorption isotherms
(Springer, 2018-11)
A new approach model was developed for the pore size characterization of carbon porous materials, using adsorption gases. The experimental adsorption isotherms of CO2 and N2 onto carbon nanoparticles were used to test the ...
Additional constraints in adsorption-desorption kinetics
(American Physical Society, 2009-02)
In this work, the adsorption-desorption kinetic in the framework of the lattice gas model is analyzed. The transition probabilities are written as an expansion of the occupation configurations. Due to that, the detail ...
Adsorption kinetic, thermodynamic and desorption studies of phosphate onto hydrous niobium oxide prepared by reverse microemulsion method
(SPRINGER, 2010)
A type of Nb(2)O(5)center dot 3H(2)O was synthesized and its phosphate removal potential was investigated in this study. The kinetic study, adsorption isotherm, pH effect, thermodynamic study and desorption were examined ...
