Abstract :

This work dealt with synthesis and characterization of modified polyvinyl membrane cross�linked on polyester fabric by using three different aldehyde solutions namely: formaldehyde, acetaldehyde and gluteraldehyde. Scanning electron microscope and transition microscope were used to study the surface morphology of the produced membranes and to follow membrane structure changes due to changing cross-linking agents. The obtained results showed that optimum conditions of aldehyde cross-linking concentrations of the membranes are those prepared by using 10% formaldehyde with 1.5% gluteraldehyde. These conditions gave the prepared membranes excellent mechanical properties and also good results in the filtration of waste water containing high amounts of organic matter and some elements.
