A survey of recent literature on zeolite membrane preparation reveals that synthesis processes, even for well-known zeolite structures (i.e., MFl, LTA), are still carried out batchwise, using a hydrothermal route to produce a thin layer from hydrogels or sols containing the corresponding nutrients. As a general rule, the reactant mixture in contact with the support changes in composition with time provoking a reduction of the membrane quality.

Any change may contribute to the dissolution of the original polymer which might be antigenic as we have already observed for several water soluble synthetic macromolecules [13]. Our choice of the low molecular weight dextran for the preparation of the hydrogel membrane is mainly intended to avoid this problem. At present, the same dextran is used as a plasma expander clinically, but higher molecular...
