ABSTRACT

A nanocomposite consisting of Fe3O4 and MWCNT was produced via sol-gel technique using FeCl3 along with MWCNTby calcination at 300oC. The degradation effect of rhodamine B dye has been investigated under UV illumination in adarkroom. The degradation reaction was studied by monitoring the discoloration of dye as a function of irradiation time usingUV-visible spectrophotometeric technique. The Fe3O4-MWCNT samples have continuous degradation ability under the UVillumination with the first order kinetics and the dye removal was better than in the pristine Fe3O4. The resultant compositecatalyst was found to be efficient for the photo-Fenton reaction of the dye.
