Abstract

Backgrounds and Objectives: Anthraquinone dyes such as reactive blue29 in water resources and industrial wastewater effluents are one of the most environmental setbacks in many countries. Various methods have been considered to remove these dyes One of which is adsorption.Materials and Methods: All adsorption experiments were conducted in different pHs and various concentrations of adsorbents. The initial concentration of REACTIVE BLUE 29 chosen in this study was 30mg/L. ADSORPTION ISOTHERMs were determined and correlated with Longmuir, Freundlich and BET models.Results: The maximum adsorption capacity of REACTIVE BLUE 29 onto single wall carbon nanotubes was 496mg/g. Results showed that the best pH for adsorption was 5 followed by pH3 and 8. Kinetic study showed that the equilibrium time for adsorption of RB 29 to SWCNT is 4 hr.Conclusion: According to the results obtained BET isotherm fitted well the experiment. It shows the adsorption of REACTIVE BLUE 29 onto single wall carbon nanotubes is multilayers and the mechanism of SWCNTs adsorption toward RB29 is based on weak van der waals forces.
