Studying Performance of Dubinin-astakhov and Dubinin-raduchkevic Equations to Evaluate Nanopore Volume and Pore Size of MCM-41 Particles (TECHNICAL NOTE)
MCM-41 particles were synthesized using inorganic raw materials and Cetyltrimethylammonium bromide (CTAB). The textural properties and structure of MCM-41 particles were characterized by XRD, SEM, TEM and N2 adsorption-desorption methods. To study performance of Dubinin-Astakhov and Dubinin-Raduchkevic isotherm models in evaluating mesopore volume and pore size of MCM-41 samples, the mesopore ...
متن کاملTheoretical Basis for the Dubinin-Radushkevitch (D-R) Adsorption Isotherm Equation
The Dubinin-Radushkevitch (D-R) equation, which was originally proposed as an empirical adaptation ~d'the Polanyi adsorption potential theory, has been the fundamental equation to quantitatively describe the adsorption td gases and vapors by microporous sorbents. The equation, based on the postulate that the mechanism for adsorption in micropores is that of pore-filling rather than layer-by-lay...

Novel Silica-Based Hybrid Adsorbents: Lead(II) Adsorption Isotherms
Water pollution caused by the lead(II) from the spent liquor has caught much attention. The research from the theoretical model to application fundaments is of vital importance. In this study, lead(II) adsorption isotherms are investigated using a series of hybrid membranes containing mercapto groups (-SH groups) as the hybrid adsorbents. To determine the best fitting equation, the experimental...
