The most important challenge across the globe in recent years is to meet the sufficient supply of drinking water and to reduce water pollution, one of the major problems is the waste water from the textile industry and the purification of dye based water is a challenge for many years.
In this paper we report dye degradation in textile waste water using Ag coated MWCNTs. Multi walled carbon nanotubes were synthesized using chemical vapor deposition method, using powder catalyst and the coating of Silver in MWCNTs was done by wet chemical method. Three Different silver concentrations
were taken for coating the MWCNT. These Ag coated Multiwall carbon nanotubes were characterized by X-ray Diffraction, Field Emission Scanning Electron Microscopy (FESEM) and UV spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) was used to study the morphology of the sample
and Energy dispersive X-ray analysis (EDAX) characterization was done to study the chemical composition. The multiwalled carbon nanotubes act like a absorbent which helps in dye degradation and silver has antibacterial properties which help in removing the bacteria and viruses in water. The
adsorption was tested for three different samples of Ag coated MWCNT’s using photocatalytic study. The UV intensity peaks showing the observable shift in intensity. Adsorption column test was done, using the Ag coated MWCNTs, using dye based water appears clear after the test.
