| Abstract/Summary |
The paper deals with liquid membrane transport and separation phenomena that are related to their natural counterparts. Designing of some complex multimembrane hybrid systems and their practical embodiment are presented. Metal cation fluxes and separation characteristics for a simple multimembrane hybrid system (MHS) and its variants such as Donnan dialysis-MHS (DD-MHS) and pervaporation-MHS (PV-MHS) integrated processes are presented and discussed. Experimental studies have been carried out with the use of commercial cation-exchange membranes, a liquid membrane (kerosene with D2EHPA) and the pervaporation membrane (Pervap 1000). The membrane systems were tested and recognized to exhibit selective and stable permeation rates of Zn2+ from multicomponent aqueous solutions containing zinc, calcium, magnesium, sodium, and potassium nitrates.
