Abstract
Multi-Walled Carbon Nanotubes (MWCNT)/chitosan nanocomposite can be produced by mixing the MWCNT from oil palm shells with chitosan through sonication process by adding glutaraldehyde 2,5% as a crosslinking. MWCNT made by using activated carbon resulting from the processing of solid waste oil palm shells through pyrolysis CVD method with a heating temperature of 950 °C. The results obtained were characterized by XRD showed that nano-sized particles with an average particle size of 131.0585 nm, FTIR test results indicated a shift in the C = C bonds, and SEM tests showed that the long tubular morphology MWCNT. MWCNT / chitosan nanocomposite applied as adsorbent in wastewater gold mine to adsorb ions Hg were analyzed using ICP-AES. Results of the analysis showed adsorption average above 96% with optimum contact time of 25 minutes and a flow rate of 5 mL / min.
