The second mechanism is interaction of the hydroxyl and other functional groups on the surface of the inorganic phase with polar bonds of gases such as [CO.sub.2] and [SO.sub.2].
The hydroxyl and other functional groups on the surface of inorganic phase may interact with polar bonds of gases such as [CO.sub.2] and SO2, that its result is improving the penetrant solubility in the composite membranes (31), (33).
