The rehydration process was performed from the gaseous phase; its kinetics shows single exponential form with the hydration time thyd = (17.1(3.2) h and thyd = (20.2(7.9) h for the membranes modified by the use of chloramphenicol and the use of actidion, respectively, whereas for control sample (only paramagnetic non-functional manganese pool ... ................
