An experimental and simulation study of binary adsorption in metal-organic frameworks
Published 2015“…Comparing with direct binary adsorption experiments, the Ideal Adsorbed Solution Theory (IAST) model using best-fit parameters for Langmuir isotherms of each pure fluid provides satisfactory predictions for the binary mixtures of CO2/N2 and CO2/CH4. …”

Gas adsorption and selectivity studies for porous metal-organic frameworks
Published 2016“…In this chapter, two methods have been adopted in the calculations of selectivities, dual-site Langmuir Freundlich-Ideal adsorbed solution theory (DSLF-IAST) and numerical integration-IAST (NI-IAST). MFM-202a exhibits excellent selectivities for C2s/CH4 (~7-12), C3s/CH4 (~63-105) and an inverse selectivity for C2H4/C2H6 (~0.7). …”

Nitrogen-Doped Carbon Foams Synthesized from Banana Peel and Zinc Complex Template for Adsorption of CO2, CH4, and N2
Published 2016“…The potential of the carbon foams for CO2/N2, CO2/CH4, and CH4/N2 separations was evaluated by measurement of pure fluid adsorption capacities using a gravimetric adsorption apparatus and calculation of adsorption selectivies at a range of conditions using ideal adsorption solution theory (IAST). The adsorption capacities at a 4000 kPa and 298 K were CO2 9.21 mmol·g-1, CH4 5.29 mmol·g-1, and N2 3.29 mmol·g-1.…”

Incorporation of spiropyran functionality into framework materials
Published 2016“…Notably, 1-Cu adsorbs negligible quantities of methane compared to carbon dioxide and other C2Hn hydrocarbons; the selectivities are confirmed by analysis via the ideal adsorbed solution theory (IAST) and Henry’s law. Of particular importance, 1-Cu demonstrates exceptional selectivity for acetylene, which has applicability in separation technologies for the isolation of acetylene. …”

Metal-organic frameworks for platinum group metal extraction
Published 2016“…Ideal adsorbed solution theory (IAST) was also employed to calculate and predict these selectivities and shows agreement with the results obtained using Henry’s law. …”
