Removal of Dye from Textile Dyeing Wastewater by Using Oxidized Multiwalled Carbon Nanotubes

Abstract

The batch removal of dye from textile dyeing wastewater by using nanooxides decorated multiwalled carbon nanotubes was studied under electron beam conditions. The effect of different nanooxides decorated multiwalled carbon nanotubes content and irradiation dosage was also investigated. The color removal efficiency was 94.9% in dose of 17.5kGy. The colour removal efficiency with Fe2O3 decorated multiwalled carbon nanotubes was similar to with TiO2 decorated multiwalled carbon nanotubues. The COD removal efficiency was 52.5% in the dose of 14.0kGy. When the irradiation dose of 17.5kGy, the COD removal efficiency was 98.2% with TiO2 decorated multiwalled carbon nanotubes.Overall, the study demonstrated that nanooxides decorated multiwalled carbon nanotubes can effectively remove color and COD from aqueous solution under irradiation.

Application of Electron Beam Irradiation for the Removal of Dye from Textile Effluents: A Review

“…Investigations were also conducted into the effects of various nanooxide decorations on multiwalled carbon nanotube content and radiation dose. With Fe 2 O 3 decorated multiwalled carbon nanotubes, the decolorization was 98.3% at 17.5 kGy of radiation exposure …”
