1. Mass Transfer in Synthetic Membranes
The basic mechanism of transport of solution components through synthetic membranes is being investigated. This research includes the removal of low molecular weight organic solutes from water by reverse osmosis/nanofiltration and pervaporation.
2. Fabrication of Polymeric Membranes
Membranes are being developed from novel polymeric materials. The emphasis is on the investigation of the fundamentals of membrane formation. Skills involved are casting membranes, membrane modification, evaluation of membrane properties, and examination of the microstructure of membranes using for example, SEM, SEM/EDX, FTIR, NMR and ESCA.
3. System Design and Applications
Theoretical and practical methods of describing membrane systems are being explored. Application of commercial and experimental membranes for specific water treatment and other industries is being investigated. For example, the removal of metal ions and acids rom industrial waste streams are being investigated.
4. Pervaporation Membranes
Novel membranes are being developed to remove dilute chlorohydrocarbons from wastewater by selective permeation and vaporization through a polymeric membrane.
5. Contolled Release in Biosystems
Pore-filled membranes are being developed for the controlled release of drugs in biological systems. For instance, a controlled release system is being designed using the pH dependent permeability of pore-filled membranes. Thus, a drug can be protected in a polymeric shell in the stomach and released in the intestines where the pH is higher..
