The alumina microfiltration(MF) membrane was modified with nanocrystalline TiO2 in the pore wall. The electrokinetic properties of unmodified and modified alumina membranes were characterized by streaming potential measurements during tangential filtration at various conditions of pH, ionic concentr

Desalination of seawater and NaCl solutions is of great interest as potable water sources are dramatically declining on earth. Most of the techniques used to decontaminate water involve polymeric membranes and expensive desalination processes. To improve thermal, chemical and physical resistance of

The filtration tests of electrolyte solutions performed with different ceramic membranes show that salt rejection depends on pH, salt nature and concentration. A simple correlation between streaming potential and rejection rates exits and confirms that streaming potential is a relevant parameter to

The use of inorganic membranes in pollution treatment is actually limited by the cost of such membranes. Advantages of inorganic membranes over organic ones are their chemical, thermal and pH resistance. In this study, low cost ZnAl2O4-TiO2 ultrafiltration membranes were tested for removing Cd(NO3)2

The use of ceramic membrane in liquid pollution treatment is actually limited due to the price of ceramic membrane, nevertheless these membranes are more resistant to solvent, pH and oxidation. In this work the preparation of low cost TiO2(50%)-ZnAl2O4(50%) membranes deposited on an artificial cordi

The filtration tests of electrolyte solutions performed with different ceramic membranes show that salt rejection depends on pH, salt nature and concentration. A simple correlation between streaming potential and rejection rates exits and confirms that streaming potential is a relevant parameter to

The streaming potential measured through the wall of a charged ceramic UF membrane is a relevant parameter to predict the retention properties of the considered membrane for ionic solutions. It is more satisfying than the electrophoretic measurement of the material particles used to prepare the memb

New membranes have been prepared by the electropolymerization of a new pyrrole dibenzo-18-crown-6 monomer with the pyrrole. The results present the characterization of the membrane recognition properties in the presence of different electrolytes. Films present a sensitivity to divalent cations like
