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.

用吸附动力学曲线统计矩法测定双层膜的气体输运参数

建立了一种由选择性聚合物层组成的双层膜的气体吸附动力学模型。首次导出了双层膜动力学吸附曲线的一阶和二阶矩的解析表达式。利用这些表达式提出了一种确定气体通过双层膜的膜层的渗透系数的方法。研究结果可用于评价复合膜的透气性系数。
