Evaluate the performance of Carbon Nanotubes in the removal of methylene blue from aqueous solutions؛ isotherms and kinetics studies

Scientific laboratories, industrial and agricultural wastewaters, rich in organic chemicals, are potential sources of pollution and eutrophication of natural water bodies. It is noteworthy that the number of emerging organic pollutants found in the environment is expected to increase with continually increasing applications of synthetic organic chemicals. Organic pollutants (including phenolic derivatives, polycyclic aromatic compounds, extractants, analytical reagents and dyes) are often found in the environment as a result of their wide laboratories and industrial uses]1-4[.The purpose of this study, removal of Methylene blue dyes from aqueous solutions dyes by carbon nanotube . The batch experiment was conducted to evaluate the effects of independent variables such as pH, dye concentration, dose of sorbent and contact time. The optimum conditions for basic Methylene blue dye removal were pH= 8.5, dye concentration= 12.5, absorbent dose= 0.011g and contact time= 15 min. Check isotherm and kinetic models showed that the experimental data with the Freundlich adsorption process Methylene blue (R2=0.8417) and pseudo-second (R2=0.9941) are correlated.
