In this final year research project, the research and experiment will be conducted in order to study the characteristic of chitosan-CNT in adsorbing metal ions. The comparison will be made between raw chitosan and chitosan gel in their efficiency in absorbing metal ions. The objective of the research can be summarized as below: • To extract chitosan from raw material which is crab shell and determined weight percentage of the biopolymers that can be extracted. • To construct new material which is based on chitosan and carbon nanotube this later will be used as one of the absorber. • To study the efficiency of these absorber in adsorbing metal ions from industrial waste water Generally, heavy metal ions are very dangerous for our health and also to the environment. Those heavy metal ions such as Zinc, Plumbum, nickel, cadmium and others can give a long term effect for our health. Nowadays, these metal ions are extensively found in most of the waste water from the industrial area. Regarding to the environmental issues, this project was done to determine the efficiency of the absorber in absorbing heavy metal ion from the industrial waste water. The methodology of this project starts with the extraction of the chitosan from raw material which involved several processes such as demineralization, deproteination and deacetylation. Chitosan which had been obtained will be further processed in order to produce chitosan gel and chitosan-carbon nanotube gel. The equipment will be used in determining metal ions in the solution will be FAAS. From the process which had been done, 70.81 gram of chitosan have been extracted from crab shells powder and from the data analysis, it shows that the carbon nanotube had improves the efficiency in metal ions adsorption by 16 percent compared to chitosan and 91 percent compared to chitosan gel.
