| Summary: | The safety and the health of society can be affected
by the presence of high concentration of environmental
contaminants such as copper ion in wastewater. However, it
was found that nanotechnology have shown remarkable results
in the removal of the contaminants concentration from water
by using nanomaterials. Thus, this study was carried out to
evaluate the environmental application of carbon nanotubes
for the adsorption experiment for the copper ion removal. The experiment was conducted to identify and determine the factors or the parameters that can influence the adsorption of copper ion such as pH, adsorbent dosage, contact time and
agitation speed. The characterization of the carbon nanotubes is conducted by using field emission scanning electron microscope (FESEM). For result analysis, Langmuir and Freundlich Isotherm were used in order to study the kinetics of the adsorption behavior and to determine the adsorption capacity of the carbon nanotube. Regression analysis was used in order to identify the significance of the parameters used to the percentage removal obtained. From this study, it was found that 5 mg, pH 9, 150 rpm, and 80 min are the best conditions for the adsorption of copper ions which give 96.1% of removal. |
