The broad aim of the research project is to develop high surface area chitosan functionalised carbon nanotube membranes for use as a sorbent for heavy metals and radionuclides. The specific aims are to: 1. Synthesize an anionic carbon nanotube membrane with the cationic biopolymer chitosan using ionic self-assembly; 2. characterise the physical properties of these membranes using electron microscopy, electrical/mechanical testing and nitrogen adsorption/desoprtion measurements; 3. establish the sorption performance of these composite membranes.
