Applying adsorption data to IAST Selectivity?
Hi,
The rationale you presented is not correct for IAST selectivity calculation. Two possibilities:
A) You calculate the selectivy from the Langmuir Equation, which is a constant and does not vary with the component pressures: S = (q1*b1)/(q2*b2)
B) You want to calculate IAST selectivities, which are not explicit and require iterations. The rationale for IAST calculations is presented in the chapter 5.3 in Do, D.D. (1998) Adsorption Analysis: Equilibria and Kinetics. Imperial College Press, London.
