Abstract:

The colors are classified as complex toxic organic materials, which are considered as the most important pollutants from the textile wastewater. This study aimed to investigate the feasibility of multi-walled carbon nanotubes use as adsorbents for the adsorption of methylene blue from aqueous solutions. This experimental study was performed discontinuously and studied the effects of the different parameters including contact time, pH, the initial concentration of the dye, and nanotubes dose on the dye removal of methylene blue. The maximum absorbance in the first 100 min was obtained 2 hrs. By increasing the adsorbent dose from 0.05 to 0.25 g on 100 gl-1 at the initial concentration, removal, random an for methylene blue solution 50 mg/mL, the dye removal efficiency was increased from 91.48% to 99.86% and 91.37% to99.83% and 90.87% to 99.73%. At the optimized pH=6, optimal contact time 3 hrs, the dye removal efficiency was increased from 98.45% to 99.34% and 98.25% to 99.27% and 96.58 % to 99.10%, while the initial concentration of color was decreased from 5 to 1 mg/L. Due to the small size, high surface area, regulatory network and Cristal form of unique, high reactivity, and the remarkable function of multi-wall carbon nanotubes as adsorbents for the removal of organic pollutants from water solutions, the results showed that the multiwalled carbon nanotubes are effective adsorbents for the dye removal of methylene blue.
