Determination of Gas Transport Parameters of a Bilayer Membrane Using the Method of Statistical Moments of the Sorption Kinetic Curve
摘要
Abstract
A model of gas sorption kinetics for a bilayer membrane consisting of a selective polymer layer applied to a highly permeable substrate has been developed. For the first time, analytical expressions for the first and second-order moments of the kinetic sorption curve of the bilayer membrane have been derived. These expressions have been used to propose a method for determining the permeability coefficients of the gas transport through the membrane layers of the bilayer membrane. The results of this work can be applied to evaluate the gas permeability coefficients of composite membranes.
